Previous research showed that the leaves, bark, and root bark of kedondong contains saponins, tannins, and flavonoids. Tannins have anti-diarrheal effects that work as the freeze of protein / astrigen, and may inhibit the secretion of chloride over the tannate bonding between protein in the intestines. Chemical compounds of flavonoids also have an effect as anti-diarrheal block receptors Cl 藟 in intestinal thus reducing the secretion of Cl 藟 to the intestinal lume. This research aims to know the anti-diarrheal activity of extracts kedondong leaf in mice Balb/C strain males in vivo. This research also proves kedondong leaves as an anti-diarrhea through trial efficacy of kedondong leaves as antisekretori and antimotilitas. This research using post-test only controlled group design. Analysis of statistical data normality and homogenity were tested by Kolmogorov Smirnov. If the data obtained homogenous then using ANOVA test. This research using ethanolic extracts kedondong leaf 200, 400 and 800 mg/kgBW to prove there is anti-diarrhea it makes into six treatment groups, for anti-secretory it makes into five treatment groups and anti-motility became five treatment groups. The result showed dose of ethanolic extracts kedondong leaf 800 mg/kgBW have significant value (p < 0.005). The conclusion from this extracts kedondong leaf research 800 mg/kgBW have pharmacological effects as antidiarrhea on Balb/C strain male mice with a mechanism of action as antisecretory and antimotility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-diarrhea" title="anti-diarrhea">anti-diarrhea</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-secretory" title=" anti-secretory"> anti-secretory</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-motility" title=" anti-motility"> anti-motility</a>, <a href="https://publications.waset.org/abstracts/search?q=kedondong%20leaf" title=" kedondong leaf"> kedondong leaf</a> </p> <a href="https://publications.waset.org/abstracts/33388/activity-antidiarrheal-extract-kedondong-leaf-in-balbc-strain-male-mice-invivo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33388.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">466</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2596</span> Moringa olifera Curate The Toxic Potential of CuO Nanoparticles in Oreochromis mossambicus </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhat%20Jabeen">Farhat Jabeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Asad"> Muhammad Asad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study assessed the curative potential of Moringa olifera seeds against copper oxide nanoparticles induced toxicity in Oreochromis mossambicus. In order to investigate the curative potential of M. olifera seeds, firstly we examine its chemical composition, secondary metabolites, and bioactive compounds including hydroxyl-cinnamic acids, flavanols and hydroxybenzoic acids through standard methods and high performance liquid chromatography. In current study, the potential sub-lethal toxic dose of CuO-NPs (0.12 mg/l) was investigated through pilot experiment and three non-lethal doses (low=32, medium=48 and high=96 mg/l) of M. olifera were selected on the basis of its LC50 value for O. mossambicus. The experimental fish, O. mossambicus (n=100 of approximately 20 g each) were procured from Manawan Fisheries Complex, Lahore, and acclimatized for two weeks in glass aquaria. Experiment was conducted in accordance with the guidelines of Institutional Animal Ethics Committee, Government College University Faisalabad, Pakistan. During acclimatization and experimental period, fish received the commercial fish feed at 2.5% body weight daily. In order to assess the curative effect of M. olifera against CuO NPs induced toxicity, O. mossambicus were randomly divided into five groups and were designated as control (C) without any treatment, positive control (G*) exposed to potential toxic dose of CuO-NPs at 0.12 mg/l, and three treated groups namely G1, G2, and G3 co-treated with 0.12 mg/l of CuO-NPs plus different doses of M. olifera seed extract at 32, 48, and 96 mg/l, respectively for 56 days. Fish were exposed to waterborne CuO NPs and M. olifera seed extract. CuO-NPs treatment was ceased after 28 days but the doses of M. olifera were continued for 56 days. Blood was taken after 28 and 56 days through caudal venipuncture. Liver and intestine were taken for oxidative stress and histological studies after 56 days. In M. olifera seeds, moisture contents, crude protein, lipids, carbohydrates and ash were recorded as 3.8, 37.83, 32.52, 46.12, and 7.75%, respectively on dry weight basis. Total energy was recorded as 627.36 kcal/100g. Qualitative analysis of M. olifera seeds showed the presence of terpenoids, saponins, flavonoids, alkaloids and phenolics, while its quantitative analysis showed the considerable amount of total phenolics, flavonoids, saponins, and alkaloids as 134.75, 170.15, 1.57, and 0.4 碌g/mg, respectively. Analysis of bioactive compounds in M. olifera seeds showed the presence of hydroxy-cinnamic acids (6.07 碌g/ml), flavanols (71.72 碌g/ml), and hydroxyl benzoic acids (97.82 碌g/ml). The results showed that M. oliefera seed extract at 48 and 56 mg/l was able to cure against the toxic effects of CuO-NPs. The significant changes were observed in G* and G1 for sero-hepatic enzymes, anti-oxidants and histological profile. The investigations of this study showed that M. olifera is a good curative agent against potential induced toxicity of CuO-NPs in O. mossambicus. The curative effect of M. olifera is attributed to the presence of higher amount of secondary metabolites and bioactive compounds. This study suggested the use of M. olifera to curate different ailments in fish and other organisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CuO%20nanoparticles" title="CuO nanoparticles">CuO nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=curative" title=" curative"> curative</a>, <a href="https://publications.waset.org/abstracts/search?q=Moringa%20olifera" title=" Moringa olifera"> Moringa olifera</a>, <a href="https://publications.waset.org/abstracts/search?q=Oreochromis%20mossambicus" title=" Oreochromis mossambicus "> Oreochromis mossambicus </a> </p> <a href="https://publications.waset.org/abstracts/123967/moringa-olifera-curate-the-toxic-potential-of-cuo-nanoparticles-in-oreochromis-mossambicus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123967.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2595</span> Biogenic Synthesis of ZnO Nanoparticles Using Annona muricata Plant Leaf Extract and Its Anti-Cancer Efficacy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siva%20Chander%20Chabattula">Siva Chander Chabattula</a>, <a href="https://publications.waset.org/abstracts/search?q=Piyush%20Kumar%20Gupta"> Piyush Kumar Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Debashis%20Chakraborty"> Debashis Chakraborty</a>, <a href="https://publications.waset.org/abstracts/search?q=Rama%20Shanker%20Verma"> Rama Shanker Verma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green nanoparticles have gotten a lot of attention because of their potential applications in tissue regeneration, bioimaging, wound healing, and cancer therapy. The physical and chemical methods to synthesize metal oxide nanoparticles have an environmental impact, necessitating the development of an environmentally friendly green strategy for nanoparticle synthesis. In this study, we used Annona muricata plant leaf extract to synthesize Zinc Oxide nanoparticles (Am-ZnO NPs), which were evaluated using UV/Visible spectroscopy, FTIR spectroscopy, X-Ray Diffraction, DLS, and Zeta potential. Nanoparticles had an optical absorbance of 355 nm and a net negative surface charge of ~ - 2.59 mV. Transmission Electron Microscope characterizes the Shape and size of the nanoparticles. The obtained Am-ZnO NPs are biocompatible and hemocompatible in nature. These nanoparticles caused an anti-cancer therapeutic effect in MIA PaCa2 and MOLT4 cancer cells by inducing oxidative stress, and a change in mitochondrial membrane potential leads to programmed cell death. Further, we observed a reduction in the size of lung cancer spheroids (act as tumor micro-environment) with doxorubicin as a positive control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Biomaterials" title="Biomaterials">Biomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title="nanoparticle">nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=anticancer%20activity" title="anticancer activity">anticancer activity</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO%20nanoparticles" title="ZnO nanoparticles">ZnO nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/147874/biogenic-synthesis-of-zno-nanoparticles-using-annona-muricata-plant-leaf-extract-and-its-anti-cancer-efficacy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147874.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">212</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2594</span> Antioxidant Activity and Chemical Constituents of Leaf Essential Oils of Pseuduvaria Monticola and Pseuduvaria Macrophylla (Annonaceae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hairin%20Taha">Hairin Taha</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20Narrima"> P.

Leaf extract used at 30% w/v was the most effective in reducing leaf and root damage index by 92.3% and the extent of vascular discoloration by 97.56% compared to Fusarium oxyxporum f. sp radicis lycopersici -inoculated and untreated control. A significant promotion of growth parameters (root length, shoot height, root and shoot biomass and stem diameter) was recorded on tomato cv. Rio Grande seedlings by 40.3-94.1% as compared to FORL inoculated control and by 9.6-88.8% over pathogen-free control. All S. linnaeanum aqueous extracts tested significantly stimulated the germination by 10.2 to 80.1% relative to the untreated control. FORL mycelial growth, assessed using the poisoned food technique, varied depending on plant organs, extracts, and concentrations used. Butanolic extracts were the most active, leading to 60.81% decrease in FORL mycelial growth. HPLC analysis of butanolic extract revealed the presence of thirteen phenolic compounds. Thus, S. linnaeanum can be explored as a potential natural source of antifungal and biofertilizing compounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antifungal%20activity" title="antifungal activity">antifungal activity</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC-MS%20analysis" title=" HPLC-MS analysis"> HPLC-MS analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Fusarium%20oxysporum%20f.%20sp.%20radicis-lycopersici" title=" Fusarium oxysporum f. sp. radicis-lycopersici"> Fusarium oxysporum f. sp. radicis-lycopersici</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato%20growth" title=" tomato growth"> tomato growth</a> </p> <a href="https://publications.waset.org/abstracts/90546/biocontrol-of-fusarium-crown-and-root-rot-and-enhancement-of-tomato-solanum-lycopersicum-l-growth-using-solanum-linnaeanum-l-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90546.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2592</span> Isolation and Characterization of Anti-melanoma (Skin Cancer) Compounds from Corchorus olitorius .L</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peramachi%20Sathiyamoorthy">Peramachi Sathiyamoorthy</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacop%20Gopas"> Jacop Gopas</a>, <a href="https://publications.waset.org/abstracts/search?q=Avi%20Golan%20Goldhirsh"> Avi Golan Goldhirsh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corchorus olitorius is a leafy vegetable and an industrial crop. The herb has antioxidant, anti inflammatory, and anti-cancer properties. To assay the pharmaceutical properties, aqueous extracts of leaves and seeds from C. olitorius were tested against drug resistant melanoma cell line. The test showed LC50 of the extract was 0.08碌g/ml. Aqueous seed extract exhibited higher melanoma inhibiting activity than leaf extract. Dialysis of seed extract showed that the active compound is less than 12 KDa. The compound with <3 KDa MW separated by microconcentration of seed extract showed 70.5 % inhibition of melanoma cell growth. Among the two fractions obtained by Gel filtration with G10 column, the first fraction at 1:2000 dilutions exhibited 100% inhibition of melanoma growth. The compound with Rf value 0.86 (MA4) isolated by TLC separation showed about 98% cytotoxicity against melanoma at 1: 1000 dilutions. Furthermore, HPLC separation of MA4 compound with Superdex 75 column resulted in 4 compounds. Out of 4, one compound showed melanoma inhibition. The active compound is identified by reagent methods as Strophanthidin.

Coleus aromaticus Benth leaf extract in different ionic liquids, elucidated pharmacologically important functional groups present in major constituents of the plant, namely, rosmarinic acid, caffeic acid and chlorogenic acid. In connection to distinctive appearance of functional groups in the spectrum and highest % transmittance, potassium chloride-glycerol is the best ionic liquid for green extraction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chlorogenic%20acid" title="chlorogenic acid">chlorogenic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=coleus%20aromaticus" title=" coleus aromaticus"> coleus aromaticus</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquid" title=" ionic liquid"> ionic liquid</a>, <a href="https://publications.waset.org/abstracts/search?q=rosmarinic%20acid" title=" rosmarinic acid"> rosmarinic acid</a> </p> <a href="https://publications.waset.org/abstracts/43412/spectroscopic-determination-of-functionalized-active-principles-from-coleus-aromaticus-benth-leaf-extract-using-ionic-liquids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43412.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2590</span> Antioxidant Activity and Microbiological Quality of Functional Bread Enriched with Morus Alba Leaf Extract during Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Kobus-Cisowska">Joanna Kobus-Cisowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Daria%20Szymanowska"> Daria Szymanowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Szulc"> Piotr Szulc</a>, <a href="https://publications.waset.org/abstracts/search?q=Oskar%20Szczepaniak"> Oskar Szczepaniak</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcin%20Dziedzinski"> Marcin Dziedzinski</a>, <a href="https://publications.waset.org/abstracts/search?q=Szymon%20Byczkiewicz"> Szymon Byczkiewicz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A wide range of food products is offered on the market. However, increasing consumer awareness of the impact of food on health causes a growing interest in enriched products. Cereal products are an important element of the daily diet of man. In the literature, no data was found on the impact of Morus alba preparations on the content of active ingredients and properties of wholemeal bread. Mulberry leaves (Morus alba L) are a rich source of bioactive compounds with multidirectional antioxidant activity, which means that they can be a component of new foods that prevent disease or support therapy and improve the patient's health. The aim of the study was to assess the impact of the addition of white mulberry leaf extract on the antioxidant activity of bread. It has been shown that bread can be a carrier of biologically active substances from mulberry leaves, because the addition of mulberry at a sensory acceptable level and meeting microbiological requirements significantly influenced the increase in the content of bioactive ingredients and the antioxidant activity of bread. The addition of mulberry leaf water extract to bread increased the level of flavonols and phenolic acids, in particular protocatechic, chlorogenic gallic and caffeic acid and isoquercetin and rutine, and also increased the antioxidant potential, which were microbiological stable during 5 days storage. It has been shown also that the addition of Morus alba preparations has a statistically significant effect on anti-radical activity. In addition, there were no differences in activity in DPPH 路 and ABTS 路 + tests between post-storage samples. This means that the compounds responsible for the anti-radical activity present in the bread were not inactivated during storage. It was found that the tested bread was characterized by high microbiological purity, which is indicated by the obtained results of analyzes performed for the titers of indicator microorganisms and the absence of pathogens. In the tested products from the moment of production throughout the entire storage period, no undesirable microflora was found, which proves their safety and guarantees microbiological stability during the storage period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidants" title="antioxidants">antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=bread" title=" bread"> bread</a>, <a href="https://publications.waset.org/abstracts/search?q=extract" title=" extract"> extract</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a> </p> <a href="https://publications.waset.org/abstracts/120409/antioxidant-activity-and-microbiological-quality-of-functional-bread-enriched-with-morus-alba-leaf-extract-during-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120409.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2589</span> Contrasting Patterns of Accumulation, Partitioning, and Reallocation Patterns of Dm and N Within the Maize Canopy Under Decreased N Availabilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Panpan%20Fan">Panpan Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20Ming"> Bo Ming</a>, <a href="https://publications.waset.org/abstracts/search?q=Niels%20P.%20R.%20Anten"> Niels P.

The objective of this study was to quantify the DM and N accumulation, partition, and reallocation at the single-leaf, different-organ, and individual-plant scales and clarify the responses to different levels of N availabilities. A two-year field experiment was conducted in Jinlin province, Northeast China, with three N fertilizer rates to create the different N availability levels: N0 (N deficiency), N1(low supply), and N2 (high supply). The results showed that grain N depends more on reallocations of vegetative organs compared with grain DM. Besides, vegetative organs reallocated more DM and N to grain under lower N availability, whereas more grain DM and grain N were derived from post-silking leaf photosynthesis and post-silking N uptake from the soil under high N availability. Furthermore, the reallocation amount and reallocation efficiency of leaf DM and leaf N content differed among leaf ranks and were regulated by N availability; specifically, the DM reallocation occurs mainly on senesced leaves, whereas the leaf N reallocation was in live leaves. These results provide a theoretical basis for deriving parameters in crop models for the simulation of the demand, uptake, partition, and reallocation processes of DM and N. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dry%20matter" title="dry matter">dry matter</a>, <a href="https://publications.waset.org/abstracts/search?q=leaf%20N%20content" title=" leaf N content"> leaf N content</a>, <a href="https://publications.waset.org/abstracts/search?q=leaf%20rank" title=" leaf rank"> leaf rank</a>, <a href="https://publications.waset.org/abstracts/search?q=N%20availability" title=" N availability"> N availability</a>, <a href="https://publications.waset.org/abstracts/search?q=reallocation%20efficiency" title=" reallocation efficiency"> reallocation efficiency</a> </p> <a href="https://publications.waset.org/abstracts/156413/contrasting-patterns-of-accumulation-partitioning-and-reallocation-patterns-of-dm-and-n-within-the-maize-canopy-under-decreased-n-availabilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156413.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2588</span> Reaction of Nine Candidate Wheat Lines/Mutants against Leaf Rust: Lodging and Aphid Population under Field Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Mohsan">Muhammad Mohsan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehboob%20Ur-Rahman"> Mehboob Ur-Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Sana%20Zulfiqar"> Sana Zulfiqar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shumila%20Ashfaq"> Shumila Ashfaq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brown Rust (Puccinia triticina), also known as leaf rust, pose a serious threat to wheat cultivation in the world. Nine candidate wheat lines/mutants were subjected to rust inoculation, lodging and aphid population in vivo conditions. Four lines/mutants (E-284, E-505, 2008-6 MR and 2008-14MR) were found resistant to leaf rust attack. Two lines (PGMB 15-29 and 2011-1 MR) displayed moderately resistant reactions against the disease. Three lines/mutants were depicted as susceptible to leaf rust. The lowest population of aphids, i.e., 16.67, was observed on 2008-14MR. Three lines/mutants (NN1-47, NN1-89 and PGMB 15-29) were found under zero level of lodging. The presence and absence of different leaf rust-resistant genes like Lr13, Lr34, Lr46 and Lr67 were assessed with the help of molecular markers. All the wheat lines/mutants were found loaded with leaf rust-resistant genes such as Lr13 and Lr 34, while Lr46 and Lr67 were found in 66% of wheat lines/mutants. The resistant source can be exploited in the breeding program to develop rust, aphid and lodging with race-nonspecific resistant wheat variety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wheat" title="wheat">wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=leaf%20rust" title=" leaf rust"> leaf rust</a>, <a href="https://publications.waset.org/abstracts/search?q=lodging" title=" lodging"> lodging</a>, <a href="https://publications.waset.org/abstracts/search?q=aphid" title=" aphid"> aphid</a> </p> <a href="https://publications.waset.org/abstracts/162424/reaction-of-nine-candidate-wheat-linesmutants-against-leaf-rust-lodging-and-aphid-population-under-field-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162424.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2587</span> Phytochemical Screening and Toxicological Studies of Aqueous Stem Bark Extract of Boswellia papyrifera (DEL) in Albino Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Abdulmumin">Y.

These molecules include alkaloids, polyphenols and terpenes. The latter can be extracted by different solvents, namely: water, ethanol, methanol, butanol, acetone... This is why it seemed interesting to us to evaluate in vitro the antimitotic and genotoxic effect of these secondary metabolites contained in the aqueous extract of the leaves of Peganum harmala L. by the Allium cepa L. test on meristematic cells by calculating the mitotic parameters (The mitotic index, the aberration index and the limit value of cytotoxicity).A spectrophotometric determination of secondary metabolites, namely alkaloids and flavonoids in the aqueous extract of this essence, was performed. As a result, the alkaloid content is estimated to be 28.42 渭g EC/mg extract, and the flavonoid content is 12.52 渭g EQ/mg extract. The determination of the mitotic index revealed disturbances in cell division with a highly significant difference between the negative control (distilled water) and the different samples (aqueous extracts, colchicine and quecetin). The exposure of meristematic cells to our samples resulted in a large number of chromosomal, nuclear and cellular aberrations with an aberration index reaching 16.21卤1.28% for the 4mg/ml aqueous extract and 11.71卤3.32% for the 10mg/ml aqueous extract. The limit value of cytotoxicity revealed that our samples are sublethal on Allium cepa L. meristematic cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allium%20cepa%20l." title="allium cepa l.">allium cepa l.</a>, <a href="https://publications.waset.org/abstracts/search?q=antimitotic%20and%20genotoxic%20effect" title=" antimitotic and genotoxic effect"> antimitotic and genotoxic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20leaf%20extract" title=" aqueous leaf extract"> aqueous leaf extract</a>, <a href="https://publications.waset.org/abstracts/search?q=laghouat%20%28algeria%29" title=" laghouat (algeria)"> laghouat (algeria)</a>, <a href="https://publications.waset.org/abstracts/search?q=peganum%20harmala%20l." title=" peganum harmala l."> peganum harmala l.</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20metabolites" title=" secondary metabolites"> secondary metabolites</a> </p> <a href="https://publications.waset.org/abstracts/167156/in-vitro-evaluation-of-the-antimitotic-and-genotoxic-effect-by-the-allium-cepa-l-test-of-the-aqueous-extract-of-peganum-harmala-l-leaves-laghouat-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167156.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2584</span> Phytochemical Analysis and Antioxidant Activity of Colocasia esculenta (L.)

The root is high in carbohydrates and rich in zinc. The leaves and stalks are often traditionally preserved to be eaten in dry season. Leaf juice is stimulant, expectorant, astringent, appetizer, and otalgia. Looking at the medicinal uses of the plant leaves; phytochemicals were extracted from the plant leaves and were characterized using Fourier-transform infrared spectroscopy (FTIR) to find the functional groups. Phytochemical analysis of <em>Colocasia esculenta</em> (L.) leaf was studied using three solvents (methanol, chloroform, and ethanol) with soxhlet apparatus. Powder of the leaves was employed to obtain the extracts, which was qualitatively and quantitatively analyzed for phytochemical content using standard methods. Phytochemical constituents were abundant in the leave extract. Leaf was found to have various phytochemicals such as alkaloids, glycosides, flavonoids, terpenoids, saponins, oxalates and phenols etc., which could have lot of medicinal benefits such as reducing headache, treatment of congestive heart failure, prevent oxidative cell damage etc. These phytochemicals were identified using UV spectrophotometer and results were presented. In order to find the antioxidant activity of the extract, DPPH (2,2-diphenyl-1-picrylhydrazyl) method was employed using ascorbic acid as standard. DPPH scavenging activity of ascorbic acid was found to be 84%, whereas for ethanol it was observed to be 78.92%, for methanol: 76.46% and for chloroform: 72.46%. Looking at the high antioxidant activity, <em>Colocasia esculenta</em> may be recommended for medicinal applications.

This paper aims to explore how maize deals with this trade-off through responses in SLN, LA and their underlying traits during the vegetative and reproductive growth stages. In a ten-year N fertilization trial in Jilin province, Northeast China, three N fertilizer levels have been maintained: N-deficiency (N0), low N supply (N1), and high N supply (N2). We analyzed data from years 8 and 10 of this experiment for two common hybrids. Under N deficiency, maize plants maintained LA and decreased SLN during vegetative stages, while both LA and SLN decreased comparably during reproductive stages. Canopy-average specific leaf area (SLA) decreased sharply during vegetative stages and slightly during reproductive stages, mainly because senesced leaves in the lower canopy had a higher SLA. In the vegetative stage, maize maintained leaf area at low N by maintaining leaf biomass (albeit hence having N content/mass) and slightly increasing SLA. These responses to N deficiency were stronger in maize hybrid XY335 than in ZD958. We conclude the main strategy of maize to cope with low N is to maintain plant growth, mainly by increasing SLA throughout the plant during early growth. N was too limiting for either strategy to be followed during later growth stages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leaf%20N%20content%20per%20unit%20leaf%20area" title="leaf N content per unit leaf area">leaf N content per unit leaf area</a>, <a href="https://publications.waset.org/abstracts/search?q=N%20deficiency" title=" N deficiency"> N deficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20leaf%20area" title=" specific leaf area"> specific leaf area</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20strateg" title=" maize strateg"> maize strateg</a> </p> <a href="https://publications.waset.org/abstracts/153846/adaptive-strategies-of-maize-in-leaf-traits-to-n-deficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153846.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2581</span> Effect of Aqueous Enzymatic Extraction Parameters on the Moringa oleifera Oil Yield and Formation of Emulsion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masni%20Mat%20Yusoff">Masni Mat Yusoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20H.%20Gordon"> Michael H.

A mixture of protease and cellulase enzymes was used at 3:1 (w/w) ratio. The highest oil yield of 19% (g oil/g sample) was recovered with the use of a mixture of pH 6, 1:4 material/moisture ratio, and incubation temperature, time, and shaking speed of 50 鈦癈, 12.5 hr, and 300 stroke/min, respectively. The use of pH 6 and 8 resulted in grain emulsions, while solid-intact emulsion was observed at pH 4. Upon fixing certain parameters, higher oil yield was extracted with the use of lower material/moisture ratio and higher shaking speed. Longer incubation time of 24 hr resulted in significantly (p < 0.05) similar oil yield with that of 12.5 hr, and an incubation temperature of 50 鈦癈 resulted in significantly (p < 0.05) higher oil yield than that of 60 鈦癈. In overall, each AEE parameter showed significant effects on both the MO oil yields and the emulsions formed. One of the major disadvantages of an AEE process is the formation of emulsions which require further de-emulsification step for higher oil recovery. Therefore, critical studies on the effect of each AEE parameter may assist in minimizing the amount of emulsions formed whilst extracting highest total MO oil yield possible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enzyme" title="enzyme">enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=emulsion" title=" emulsion"> emulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=Moringa%20oleifera" title=" Moringa oleifera"> Moringa oleifera</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20yield" title=" oil yield"> oil yield</a> </p> <a href="https://publications.waset.org/abstracts/21157/effect-of-aqueous-enzymatic-extraction-parameters-on-the-moringa-oleifera-oil-yield-and-formation-of-emulsion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21157.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">439</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2580</span> Development and Evaluation of New Complementary Food from Maize, Soya Bean and Moringa for Young Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Berhan%20Fikru">Berhan Fikru</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to develop new complementary food from maize, soybean and moringa for young children. The complementary foods were formulated with linear programming (LP Nutri-survey software) and Faffa (corn soya blend) use as control. Analysis were made for formulated blends and compared with the control and recommended daily intake (RDI). Three complementary foods composed of maize, soya bean, moringa and sugar with ratio of 65:20:15:0, 55:25:15:5 and 65:20:10:5 for blend 1, 2 and 3, respectively. The blends were formulated based on the protein, energy, mineral (iron, zinc an calcium) and vitamin (vitamin A and C) content of foods. The overall results indicated that nutrient content of faffa (control) was 16.32 % protein, 422.31 kcal energy, 64.47 mg calcium, 3.8 mg iron, 1.87mg zinc, 0.19 mg vitamin A and 1.19 vitamin C; blend 1 had 17.16 % protein, 429.84 kcal energy, 330.40 mg calcium, 6.19 mg iron, 1.62 mg zinc, 6.33 mg vitamin A and 4.05 mg vitamin C; blend 2 had 20.26 % protein, 418.79 kcal energy, 417.44 mg calcium, 9.26 mg iron, 2.16 mg zinc, 8.43 mg vitamin A and 4.19 mg vitamin C whereas blend 3 exhibited 16.44 % protein, 417.42 kcal energy, 242.4 mg calcium, 7.09 mg iron, 2.22 mg zinc, 3.69 mg vitamin A and 4.72 mg vitamin C, respectively. The difference was found between all means statically significance (P < 0.05). Sensory evaluation showed that the faffa control and blend 3 were preferred by semi-trained panelists. Blend 3 had better in terms of its mineral and vitamin content than FAFFA corn soya blend and comparable with WFP proprietary products CSB+, CSB++ and fulfills the WHO recommendation for protein, energy and calcium.

In many parts of the Rajasthan surface water which can be highly turbid and contaminated with fecal coliform bacteria is used for drinking purposes. The majority rely almost exclusively upon traditional sources of highly turbid and untreated pathogenic surface water for their domestic water needs. In many parts of rural areas of Rajasthan, it is still difficult to obtain clean water, especially remote habitations with no groundwater due to quality issues or depletion and limited feasibility to connect with surface water schemes due to low density of population in these areas to justify large infrastructure investment. The most viable sources are rain water harvesting, community managed open wells, private wells, ponds and small-scale irrigation reservoirs have often been the main traditional sources of rural drinking water. Turbidity is conventionally removed by treating the water with expensive chemicals. This study has to investigate the use of crushed seeds from the tree Moringa oleifera (drumstick) as a natural alternative to conventional coagulant chemicals. The use of Moringa oleifera seed powder can produce potable water of higher quality than the original source. Moringa oleifera a native species of northern India, the tree is now grown extensively throughout the tropics and found in many countries of Africa, Asia & South America. The seeds of tree contains significant quantities of low molecular weight, water soluble proteins which carries the positive charge when the crushed seeds are added to water. This protein binds in raw water with negatively charged turbid water with bacteria, clay, algae, etc. Under proper mixing, these particles make flocks, which may be left to settle by gravity or be removed by filtration. Using Moringa oleifera as a replacement coagulation in such surface sources of arid and semi-arid areas can meet the need for water purification in remote places of Rajasthan state of India. The present study accesses to find out laboratory based investigation of the effect of seeds of Moringa tree on its coagulation effectiveness (purification) using turbid water samples of surface source of the Rajasthan state. In this study, moringa seed powder showed that filtering with seed powder may diminish water pollution and bacterial counts. Results showed Moringa oleifera seeds coagulate 90-95% of turbidity and color efficiently leading to an aesthetically clear supernatant & reduced about 85-90% of bacterial load reduction in samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial%20load" title="bacterial load">bacterial load</a>, <a href="https://publications.waset.org/abstracts/search?q=coagulant" title=" coagulant"> coagulant</a>, <a href="https://publications.waset.org/abstracts/search?q=turbidity" title=" turbidity"> turbidity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20purification" title=" water purification"> water purification</a> </p> <a href="https://publications.waset.org/abstracts/78012/potential-of-water-purification-of-turbid-surface-water-sources-in-remote-arid-and-semi-arid-rural-areas-of-rajasthan-by-moringa-oleifera-drumstick-tree-seeds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78012.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2578</span> Extraction, Isolation and Comparative Phtochemical Study of Aegle Marmelos, Calendula Officinalis and Fenugreek</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nitin%20Rajan">Nitin Rajan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kashif%20Shakeel"> Kashif Shakeel</a>, <a href="https://publications.waset.org/abstracts/search?q=Shashank%20Tiwari"> Shashank Tiwari</a>, <a href="https://publications.waset.org/abstracts/search?q=Shachan%20Sagar"> Shachan Sagar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: - Aegle Marmelos (Bael) leaf extract is taken twice daily to treat ophthalmia, ulcers, and intestinal worms, among other ailments.

Noise has seriously affected people's normal life, study and work. In addition, noise has seriously affected the city's ecological environment and the migration of birds. Therefore, it is urgent to control the noise. As one of natural noise-reducing materials, plants have been paid more and more attention. In urban landscape design, it is very important to choose plant species with good noise reduction effect to the sustainable development of urban ecology. The aim of this paper is to find out the characteristics of the plant with good noise reduction effect and apply it in urban landscape design. This study investigated the vibration of leaves of six plant species in a sound field using a Keyence (IG-1000/CCD) Laser Micrometer. The results of the experiments showed that the vibration speed of plant leaves increased obviously after being stimulated by sound source, about 5-10 times. In addition, when driven by the same sound, the speed of all leaves varied with the difference of leaf thickness, leaf size and leaf mass. The speed of all leaves would increase with the increase of leaf size and leaf mass, while those would decrease with the increase of leaf thickness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landscape%20design" title="landscape design">landscape design</a>, <a href="https://publications.waset.org/abstracts/search?q=leaf%20vibration" title=" leaf vibration "> leaf vibration </a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20attenuation" title=" noise attenuation"> noise attenuation</a>, <a href="https://publications.waset.org/abstracts/search?q=plants%20configuration" title=" plants configuration"> plants configuration</a> </p> <a href="https://publications.waset.org/abstracts/82980/selection-of-landscape-plant-species-a-experiment-of-noise-reduction-by-vibration-of-plant-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82980.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">233</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2576</span> Effects of Collection Time on Chemical Composition of Leaf Essential Oils of Hoslundia opposita</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20E.%20Ogunjinmi">O.

It has been established that several factors affect the component of the plants such as the texture of the soil, relative humidity, wind, and collection time. This study is aimed at investigating the effect of collection time on the chemical composition of this essential oil. Pulverized leaves (500 g) of Hoslundia opposite harvested in the morning (7 am) and afternoon (2 pm) of the same day were separately hydrodistilled using Clevenger apparatus to obtain the essential oils from the leaves. The leaf oils collected in the morning (7 am) and afternoon (2 pm) harvests yielded 0.54 and 0.65 %w/w respectively. Analysis of the leaf oil obtained in the morning, using gas chromatography (GC) and gas chromatography combined mass spectrometry (GC-MS) revealed the presence of twenty-three (23) compounds which made up 81.8% of the total oil while nineteen (19) compounds (93.2%) were identified in the afternoon leaf essential oil. The most abundant components of the leaf oil collected in the morning (7 am) harvest were p-cymene (28.7%), sabinene (7.1%) and 1,8-cineole (6.6%) Meanwhile the major components of leaf oil in the afternoon (2 pm) harvest were p-cymene (26.4%), thymol (15.3%), 1,8-cineole (15.0%) and g-terpinene (10.4%). The composition pattern of leaf oil obtained in the morning and afternoon harvests of Hoslundia opposite revealed significant differences in qualitative and quantitative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=essential%20oil" title="essential oil">essential oil</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoslundia%20opposita" title=" Hoslundia opposita"> Hoslundia opposita</a>, <a href="https://publications.waset.org/abstracts/search?q=para%20cymene" title=" para cymene"> para cymene</a>, <a href="https://publications.waset.org/abstracts/search?q=1" title=" 1"> 1</a>, <a href="https://publications.waset.org/abstracts/search?q=8-cineole" title=" 8-cineole "> 8-cineole </a> </p> <a href="https://publications.waset.org/abstracts/18048/effects-of-collection-time-on-chemical-composition-of-leaf-essential-oils-of-hoslundia-opposita" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18048.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2575</span> Phytochemical and in vitro Antimicrobial Screening of Extract of Sunflower Chrysanthlum indicum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Ibrahim">I.

For this study, rats were divided into four groups namely control group where rats were orally administered distilled water, only combination treated group, piroxicam treated group and combination pre-administered piroxicam treated group. Each group of rats consisted of six animals. Melatonin at a dose of 20mg/kg body weight and antioxidant rich Murraya koenigii leaf extract at a dose of 50 mg /kg body weight were successively administered at 30 minutes interval one hour before oral administration of piroxicam at a dose of 30 mg/kg body weight to Wistar rats in the combination pre-administered piroxicam treated group. The rats of the animal group which was only combination treated were administered both the drugs respectively without piroxicam treatment whereas the piroxicam treated animal group was administered only piroxicam at 30mg/kg body weight without any pre-treatment with the combination. Macroscopic examination along with histo-pathological study of gastric tissue using haemotoxylin-eosin staining and alcian blue dye staining showed protection of the gastric mucosa in the combination pre-administered piroxicam treated group. Determination of adherent mucus content biochemically and collagen content through Image J analysis of picro-sirius stained sections of rat gastric tissue also revealed protective effects of the combination in piroxicam mediated toxicity. Gelatinolytic activity of piroxicam was significantly reduced by pre-administration of the drugs which was well exhibited by the gelatin zymography study of the rat gastric tissue. Mean ulcer index determined from macroscopic study of rat stomach reduced to a minimum (0卤0.00; Mean 卤 Standard error of mean and number of animals in the group=6) indicating the absence of ulcer spots on pre-treatment of rats with the combination. Gastro-friendly prostaglandin (PGE2) which otherwise gets depleted on piroxicam treatment was also well protected when the combination was pre-administered in the rats prior to piroxicam treatment. The requirement of the individual drugs in low doses in this combinatorial therapeutic approach will possibly minimize the cost of therapy as well as it will eliminate the possibility of any pro-oxidant side effects on the use of high doses of antioxidants. Beneficial activity of this combination therapy in the rat model raises the possibility that similar protective actions might be also observed if it is adopted by patients consuming NSAIDs like piroxicam. However, the introduction of any such therapeutic approach is subject to future studies in human. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gastro-protective%20action" title="gastro-protective action">gastro-protective action</a>, <a href="https://publications.waset.org/abstracts/search?q=melatonin" title=" melatonin"> melatonin</a>, <a href="https://publications.waset.org/abstracts/search?q=Murraya%20koenigii%20leaf%20extract" title=" Murraya koenigii leaf extract"> Murraya koenigii leaf extract</a>, <a href="https://publications.waset.org/abstracts/search?q=piroxicam" title=" piroxicam"> piroxicam</a> </p> <a href="https://publications.waset.org/abstracts/59005/gastro-protective-actions-of-melatonin-and-murraya-koenigii-leaf-extract-combination-in-piroxicam-treated-male-wistar-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59005.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">311</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2573</span> Antioxidant Effects of Withania Somnifera (Ashwagandha) on Brain </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manju%20Lata%20Sharma">Manju Lata Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Damage to cells caused by free radicals is believed to play a central role in the ageing process and in disease progression. Withania somnifera is widely used in ayurvedic medicine, and it is one of the ingredients in many formulations to increase energy, improve overall health and longevity and prevent disease. Withania somnifera possesses antioxidative properties. The antioxdant activity of Withania somnifera consisting of an equimolar concentration of active principles of sitoindoside VII-X and withaferin A. The antioxidant effect of Withania somnifera extract was investigated on lipid peroxidation (LPO), superoxide dismutase (SOD) and catalase (CAT) activity in mice. Aim: To study the antioxidant activity of an extract of Withania somnifera leaf against a mice model of chronic stress. Healthy swiss albino mice (3-4 months old) selected from an inbred colony were divided in to 6 groups. Biochemical estimation revealed that stress induced a significant change in SOD, LPO, CAT AND GPX. These stress induced perturbations were attenuated Withania somnifera (50 and 100 mg/kg BW). Result: Withania somnifera tended to normalize the augmented SOD and LPO activities and enhanced the activities of CAT and GPX. The result indicates that treatment with an alcoholic extract of Withania somnifera produced a significant decrease in LPO ,and an increase in both SOD and CAT in brain mice. This indicates that Withania somnifera extract possesses free radical scavenging activity . <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Withania%20somnifera" title="Withania somnifera">Withania somnifera</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20peroxidation" title=" lipid peroxidation"> lipid peroxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=brain" title=" brain"> brain</a> </p> <a href="https://publications.waset.org/abstracts/56678/antioxidant-effects-of-withania-somnifera-ashwagandha-on-brain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56678.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2572</span> Comparation of Essential Oils Composition from the Leaves and Flowers of Salvia pratensis L.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valerija%20Dunki%C4%87">Valerija Dunki膰</a>, <a href="https://publications.waset.org/abstracts/search?q=Nada%20Bezi%C4%87"> Nada Bezi膰</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Salvia is a genus of the well-known medicinal plant of Lamiaceae family and growing wild throughout the world. This abstract reports the comparation of the essential oils from leaves and flowers composition of Salvia pratensis L. from mountain Velebit, Croatia. Water distilled essential oils from aerial parts of investigation plant have been analysed by GC and GC/MS using VF-5ms capillary column. Fifty-three constituents, representing 99.4% of the leaf oil composition; 51 constituents, representing 86.8% of the flower oil composition. Essential oil yield varied from 0.9% to 1.3% in the leaf and flower parts of the plant. The flower essential oil was characterized by a high concentration of E-caryophyllene (21.9%) and germacrene D (10.2%). Major constituents of the leaf oil were linalool (17.7%), linalool acetate (15.3%) and limonene (9.8%). The comparative results clearly indicated that the leaf and flower oil compositions of S. pratensis were quite different in terms of major components content.

The main function of this damper in these vehicles is protection against damage and providing comfort for drivers by creating suspension between road and vehicle. This paper presents a new device, circular leaf spring damper, which is frequently used on vehicles, aiming to gain seismic protection of structures. Finite element analyses were conducted on several one-story structures using finite element software (Abaqus, v6.10-1). The time history analysis was conducted on the records of Kobe (1995) and San Fernando (1971) ground motions to demonstrate the advantages of using leaf spring in structures as compared to simple bracing system. This paper also suggests extending the use of this damper in structures, considering its large control force despite high cycle fatigue properties and low prices. <p
