The extracts were subjected to microwave plasma Atomic Emission Spectroscopy (MPES) to determine the following metals Se, Ag, Fe, Cu, Ni, As, Co, Mn, and Al. From the result, Ag, Cu, Ni, and Co are of very negligible concentrations in the plant extract. However, Seleniun is found to be 0.530 (mg/kg) in the plant methanolic extract. Iron, on the other hand, was found to be 3.712 (mg/kg) in the plant extract. Arsenic was found to be 0.506 and 1.301 (mg/kg) in both methanolic and petroleum spirit extracts of the plant material. The concentration of aluminium was found to be of the range of 3.050mg/kg in the plant. Functional group analysis of the plant extracts was also carried out using Fourier transform infrared (FTIR) spectroscopy which showed the presence of some functional groups. The results of this study suggest some merit in the popular use of the plant in herbal medicine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aspillia%20kotschyi" title="Aspillia kotschyi">Aspillia kotschyi</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20group" title=" functional group"> functional group</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR" title=" FTIR"> FTIR</a>, <a href="https://publications.waset.org/abstracts/search?q=MPES" title=" MPES"> MPES</a> </p> <a href="https://publications.waset.org/abstracts/155497/chemical-analyses-of-aspillia-kotschyi-sch-bipex-hochst-oliv-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155497.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">118</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">4059</span> Seed Priming, Treatments and Germination</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atakan%20Efe%20Akp%C4%B1nar">Atakan Efe Akpınar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeynep%20Demir"> Zeynep Demir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seed priming technologies are frequently used nowadays to increase the germination potential and stress tolerance of seeds.

Madasamy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The discovery and development of newer antibiotics are limited with the increase in resistance of such multi-drug resistant bacteria creating the need for alternative new therapeutic agents. The recently discovered New Delhi Metallo-betalactamase-1 (NDM-1), which confers antibiotic resistance to most of the currently available β-lactams, except colistin and tigecycline, is a global concern. Several antibacterial drugs approved are natural products or their semisynthetic derivatives, but plant extracts remain to be explored to find molecules that are effective against NDM-1 bacteria. Therefore, it is necessary to explore the possibility of finding new and effective antibacterial compounds against NDM-1 bacteria. In the present study, we have screened a diverse set South Indian plant species, and report most plant species as a potential source for antimicrobial compounds against NDM-1 bacteria. Ethanol extracts from the leaves of taxonomically diverse South Indian medicinal plants were screened for antibacterial activity against NDM-1 E. coli using streak plate method. Among the plant screened against NDM-1 E. coli, the ethanol extracts from many plant extracts showed minimum bactericidal concentration between 5 and 15 mg /ml and MIC between 2.54 and 5.12 mg/ml. These extracts also showed a potent synergistic effect when combined with antibiotics colistin and tetracycline. Combretum albidum that was effective was taken for further analysis. At 5mg/L concentration, these extracts inhibited the NDM-1 enzyme in vitro, and residual activity for Combretum albidum was 33.09%. Treatment of NDM-1 E. coli with the extracts disrupted the cell wall integrity and caused 89.7% cell death. The plant extract of Combretum albidum that was effective was subjected to fractionation and the fraction was further subjected to HPLC, LC-MS for identification of antibacterial compound. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title="antibacterial activity">antibacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=combretum%20albidum" title=" combretum albidum"> combretum albidum</a>, <a href="https://publications.waset.org/abstracts/search?q=Escherichia%20coli" title=" Escherichia coli"> Escherichia coli</a>, <a href="https://publications.waset.org/abstracts/search?q=NDM-1" title=" NDM-1"> NDM-1</a> </p> <a href="https://publications.waset.org/abstracts/60837/screening-and-isolation-of-lead-molecules-from-south-indian-plant-extracts-against-ndm-1-producing-escherichia-coli" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60837.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">455</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">4053</span> Efficacy of Plant Extracts on Insect Pests of Watermelon and Their Effects on Nutritional Contents of the Fruits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatai%20Olaitan%20Alao">Fatai Olaitan Alao</a>, <a href="https://publications.waset.org/abstracts/search?q=Thimoty%20Abiodun%20Adebayo"> Thimoty Abiodun Adebayo</a>, <a href="https://publications.waset.org/abstracts/search?q=Oladele%20Abiodun%20Olaniran"> Oladele Abiodun Olaniran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This experiment was conducted at Ladoke Akintola University of Technology, Ogbomoso, Teaching and Research farm during the major and minor planting season , 2017 to determine the effects of Annona squamosa (Linn.) and Moringa oleifera (Lam) extracts on insect pests of watermelon and their effects on nutritional contents of watermelon fruits. Synthetic insecticide and untreated plots were included in the treatments for comparison. Selected plants were prepared with cold water and each plant extracts was applied at three different concentrations (5,10 and 20% v/v). Data were collected on population density of insect pests, number of aborted fruits, number of defoliated flowers , the yield was calculated in t/ha, nutritional and fatty acid contents were determine using gas chromatography. The results show that the two major insects were observed - Diabrotica undicimpunctata and Dacus cucurbitea. The tested plant extracts had about 65% control of the observed insect pests when compared with the control and the two plant extracts had the same insecticidal efficacy. However, the applied plant extracts at 20% v/v had higher insecticidal effects than the other tested concentrations. Significant higher yield was observed on the plant extracts treated plants compared with untreated plants which had the least yield() but none of the plant extracts performed effectively as Lambdachyalothrin in the control of insect pests and yield. Meanwhile, the tested plant extracts significantly improved the proximate and fatty acid contents of watermelon fruits while Lambdachyalothrin contributed negatively to the nutritional contents of watermelon fruits.

Eight plant species used by the traditional healers and local people to treat fungal infections were selected for further phytochemical analysis and biological assay. The selected plant species were extracted with solvent of various polarities such as acetone, methanol, ethanol, hexane, dichloromethane, ethyl acetate and water. Leaf, roots and bark extracts of<em> Maerua juncea</em> Pax, <em>Albuca seineri</em> (Engl & K.

This study was aimed to evaluate the phytochemical constituents and antibacterial activity of the tuber skin extracts of the plant species. Methanol, acetone, and water were used to obtain the solvent extractions of the skin peel extracts. Concentrated extracts of skin peel were tested using previously established qualitative phytochemical assays. The antibacterial efficacy of methanol tuber skin extract was tested against Gram-negative and positive microorganisms, namely, Klebsiella pneumonia, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, and Mycobacterium tuberculosis strains. Agar well diffusion method was employed to determine the zone of inhibition of the plant extracts. Obtained data were statistically analyzed. Methanol extracts of Flemingia vestita were found to be effective against Bacillus subtilis and Mycobacterium tuberculosis at concentrations of 0.5 mg/ml. The reported zone of inhibition for the two strains was 13.3mm ± 0.57 and 16.3mm ± 4.9, respectively. However Klebsiella pneumoniae, Pseudomonas aeruginosa and Escherichia coli were resistant to the plant extracts with no zone of inhibition. Alkaloids, glycosides, and phenols were found to be present in aqueous, methanol, and acetone extracts of the plant in qualitative phytochemical analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flemingia%20vestita" title="flemingia vestita">flemingia vestita</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title=" antibacterial activity"> antibacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemical%20screening" title=" phytochemical screening"> phytochemical screening</a>, <a href="https://publications.waset.org/abstracts/search?q=well%20diffusion%20method" title=" well diffusion method"> well diffusion method</a> </p> <a href="https://publications.waset.org/abstracts/146834/qualitative-phytochemical-screening-and-antibacterial-evaluation-of-sohphlang-flemingia-vestita" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146834.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">109</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">4050</span> Phytochemical and Antibacterial Activity of Chrysanthellum indicum (Linn) Extracts </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20L.%20Ibrahim">I.

Seven plant extracts (Plantago mediastepposa, Quercusc infectoria, Punic granatum, Thymus lcotschyana, Ginger officeinals, Rhus angustifolia and Cinnamon) were collected from different regions of Kurdistan region of Iraq. These plants’ extracts were dissolved in absolute ethanol and distillate water, after which they were assayed in vitro as an antimicrobial activity against Candida tropicalis, Candida albicanus, Candida dublinensis, Candida krusei and Candida glabrata also against 2 Gram-positive (Bacillus subtilis and Staphylococcus aureus) and 3 Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa and Klebsilla pneumonia). The antimicrobial activity was determined in ethanol extracts and distilled water extracts of these plants. The ethanolic extracts of Q. infectoria showed the maximum activity against all species of Candida fungus. The minimum inhibition zone of the Punic granatum ethanol extracts was 0.2 mg/ml for all microorganisms tested. Klebsilla pneumonia was the most sensitive bacterial strain to Quercusc infectoria and Rhus angustifolia ethanol extracts.

It is a major limiting factor in amaranth production. Field experiments were conducted during 2022 and 2023 with the aim of assessing insecticidal potential of five selected plant leaf extracts, namely Moringa oleifera, Azadiractha indica A. Juss , Balanites aegyptiaca Del., Momordica balsamina and Hyptis suaveolens using Lambda.cyhalothrin 2.5 EC, a synthetic insecticide as a check. The experiment was conducted in a randomized complete block design (RCBD) replicated three times. Results showed that A.indica and H.suaveolous were more effective in reducing H .recurvalis population, leaf perforation, leaf damaged and improved amaranth plant growth and yield. This was closely followed by B. aegyptiaca and M. balsamina while M. oleifera had the lowest effect on the use of pest population and damage. Lambda.cyhalothrin, a synthetic insecticide, was found to be superior to the five plant extracts. The result showed that A. indica and H. suaveolens improved the growth and yield of amaranth during the study period. The study, therefore, recommended the two plant extracts for the control of leaf webber caterpillar (H. recurvalis) to limited resource farmers and as a good alternative to Lambda.cyhalothrin 2.5EC in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amaranth" title="Amaranth">Amaranth</a>, <a href="https://publications.waset.org/abstracts/search?q=leaf%20Webber%20plant%20extracts" title=" leaf Webber plant extracts"> leaf Webber plant extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=Lambda%20cyhalothrin" title=" Lambda cyhalothrin"> Lambda cyhalothrin</a>, <a href="https://publications.waset.org/abstracts/search?q=rainfed" title=" rainfed"> rainfed</a> </p> <a href="https://publications.waset.org/abstracts/192547/pesticidal-potential-of-selected-aqueous-plant-extracts-for-the-control-of-webber-caterpillar-hymenis-recurvalis-fab-infestation-on-amaranthus-in-kasheregombe-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192547.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">18</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">4045</span> Crude Extracts of Medicinal Plants Can Inhibit Some Bacteria of Clinical Importance in Minced Meat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chika%20C.%20Ogueke">Chika C.

Soxhlet extraction and cold ethanol extraction methods were used for the extraction of the dried and ground plant samples. Well in agar diffusion method was used for the antimicrobial screening at different concentrations of 25mg/ml, 50mg/ml, 100mg/ml and 200mg/ml on E.coli and B.subtilis. The preservative effects of the extracts at 0.1%, 0.2% and 0.3% singly and in combination were determined in minced meat using E. coli and B. subtilis as test isolates. Phytochemical analysis was also conducted on the extracts using standard analytical methods. E.hirta cold and A.boonei cold extracts gave the highest zone of growth inhibition on E. coli and B.substilis with 20mm zone diameter at 200mg/ml concentration. Phytochemical analysis revealed the presence of alkaloids, flavonoids, tannins, saponins and cardiac glycosides. A.boonei at 0.1, 0.2 and 0.3% produced a log cycle reduction on the growth of E.coli. Mixture of A. boonei and E. hirta extracts (1:1) at 0.1% and 0.2% also produced a log cycle reduction on the growth of E.coli and B. subtilis, however the A. boonei extracts had more significant effect on the isolates. The observed antimicrobial activities are attributed to the phytochemicals identified in the extracts. The results reveal the potentials of plant extracts as natural antimicrobial preservatives in minced meat. Thus the crude extracts can act as inhibitors of bacteria in a food system.

The percentage yield of the extracts ranged from 3.90 to 6.53% and 9.63 to 10.20% respectively for the plant materials. Phytochemical screening of the plant materials revealed the presence of alkaloids, saponins, tannins, phlobatanins, phenols, anthraquinones and glycosides.

All the extracts remarkably inhibited the growth of Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae, Salmonella typhii, Aspergillus flavus, Candida albicans and Candida glabrata. The mean diameter of the zone of inhibition exhibited by the extracts was between 8.00 and 22.33mm while the minimum inhibitory concentration (MIC) was between 2.5 and 200mg/ml. However, the cold water extracts of L. trichiliodes stem bark exhibited no inhibitory activity against the organisms. The results of this investigation confirmed the folkloric uses of these plants for the treatment of various infectious diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title="antimicrobial">antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=infectious%20diseases" title=" infectious diseases"> infectious diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemical" title=" phytochemical"> phytochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20heudelotii" title=" T. heudelotii"> T. heudelotii</a> </p> <a href="https://publications.waset.org/abstracts/61948/antimicrobial-and-phytochemical-screening-of-stem-bark-extracts-of-lovoa-trichiliodes-harm-and-trichilia-heudelotii-planc-harm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61948.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">286</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">4043</span> In vitro Investigation of Genotoxic and Antigenotoxic Properties of Gunnera perpensa Roots Extracts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20H.%20Mfengwana">P.

The uses of this plant include menstrual pain relief, treatment of infertility and promotion of easy labour. However, even though this plant species has been reported to possess numerous medicinal properties, to author’s best knowledge, its safety has not been investigated. Thus, this study was aimed at investigating the genotoxicity and antigenotoxicity of Gunnera perpensa aqueous, methanol and dichloromethane extracts. The in vitro toxicity of the plant extracts was assessed with the neutral red uptake (NRU) test. Genotoxic and antigenotoxic properties of Gunnera perpensa were investigated using high-throughput assays: bacterial Vitotox test and the alkaline comet assay with and without S9 activation on human C3A cells. Ethyl Methanesulfonate (EMS) and 4-nitroquinoline-oxide (4-NQO) were used as positive controls, respectively. All extracts showed toxicity in a dose-dependent manner; however, that does not mean they were all genotoxic. Methanol extract did show genotoxicity with S9 (metabolism) only at the highest concentration of 500 µg/ml due to increased DNA damage observed, however, no genotoxicity was observed from other concentrations. Therefore, the results show that Gunnera perpensa extracts are genotoxic and not safe for human use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antigenotoxicity" title="antigenotoxicity">antigenotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=comet%20test" title=" comet test"> comet test</a>, <a href="https://publications.waset.org/abstracts/search?q=genotoxicity" title=" genotoxicity"> genotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunnera%20perpensa" title=" Gunnera perpensa"> Gunnera perpensa</a>, <a href="https://publications.waset.org/abstracts/search?q=vitotox%20assay" title=" vitotox assay"> vitotox assay</a> </p> <a href="https://publications.waset.org/abstracts/100204/in-vitro-investigation-of-genotoxic-and-antigenotoxic-properties-of-gunnera-perpensa-roots-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100204.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">132</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">4042</span> Insecticidal Effects of Plant Extracts of Thymus daenensis and Eucalyptus camaldulensis on Callosobruchus maculatus (Coleoptera: Bruchidae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Afsoon%20Danesh%20Afrooz">Afsoon Danesh Afrooz</a>, <a href="https://publications.waset.org/abstracts/search?q=Sohrab%20Imani"> Sohrab Imani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ahadiyat"> Ali Ahadiyat</a>, <a href="https://publications.waset.org/abstracts/search?q=Aref%20Maroof"> Aref Maroof</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Ostadi"> Yahya Ostadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study has been investigated for finding alternative and safe botanical pesticides instead of chemical insecticides.

The aim of our study was to obtain silver nanoparticles, using plant wastes extracts resulted in the essential oils extraction process: Thymus vulgaris L., Origanum vulgare L., Lavandula angustifolia L., and in hemp processing for seed and fibre, Cannabis sativa. Firstly, we obtained aqueous extracts of thyme, oregano, lavender, and hemp (two monoicous and one dioicous varieties), all harvested in western part of Romania. Then, we determined the chemical composition of the extracts by liquid-chromatography coupled with diode array and mass spectrometer detectors. The compounds identified in the extracts were in agreement with earlier published data, and the determination of the antioxidant activity of the obtained extracts by DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) assays confirmed their antioxidant activity due to their total polyphenolic content evaluated by Folin-Ciocalteu assay. Then, the silver nanoparticles (AgNPs) were successfully biosynthesised, as was demonstrated by UV-VIS, FT-IR spectroscopies, and SEM, by reacting AgNO₃ solution and plant extracts. AgNPs were spherical in shape, with less than 30 nm in diameter, and had a good bactericidal activity against Gram-positive (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae, Pseudomonas fluorescens). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plant%20wastes%20extracts" title="plant wastes extracts">plant wastes extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20composition" title=" chemical composition"> chemical composition</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20performance%20liquid%20chromatography%20mass%20spectrometer" title=" high performance liquid chromatography mass spectrometer"> high performance liquid chromatography mass spectrometer</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC-MS" title=" HPLC-MS"> HPLC-MS</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electron%20microscopy" title=" scanning electron microscopy"> scanning electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/129078/green-synthesis-of-silver-nanoparticles-mediated-by-plant-by-product-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129078.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">180</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">4038</span> Plant Extracts: Chemical Analysis, Investigation of Antioxidant, Antibacterial, and Antifungal Activities and Their Applications in Food Packaging Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Sabbah">Mohammed Sabbah</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Al-Asmar"> Asmaa Al-Asmar</a>, <a href="https://publications.waset.org/abstracts/search?q=Doaa%20Abu-Hani"> Doaa Abu-Hani</a>, <a href="https://publications.waset.org/abstracts/search?q=Fuad%20Al-Rimawi"> Fuad Al-Rimawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plant extracts are an increasingly popular natural product with a wide range of potential applications in food, industrial, and health care industries. They are rich in polyphenolic compounds and flavonoids, which have been demonstrated to possess a variety of beneficial properties, including antimicrobial and antioxidant activity. Plant extracts have been found to possess antimicrobial activity against a variety of foodborne pathogens and can be used as a natural preservative to extend the shelf life of food products. They have also strong antioxidant activity, which can reduce the formation of free radicals and oxidation of food components. Recently there is an increase interest in bio-based polymers to be used as innovative “bioplastics” for industrial exploitation e.g. packaging materials for food products. Additionally, incorporation of active compounds (e.g. antioxidants and antimicrobials) in bio-polymer materials is of particular interest since such active polymers can be used as active packaging materials (with antimicrobial and antioxidant activity). In this work, different plant extracts have been characterized for their phenolic compounds, flavonoids content, antioxidant activity (both as free radical scavenging ability and reducing ability), and antimicrobial activity against gram positive and negative bacteria (Escherichia coli; Staphylococcus aureus, and Pseudomonas aeruginosa) as well as antifungal activities (against yeast, mold and Botrytis cinera/a plant pathogen). Results showed that many extracts are rich with polyphenolic compounds and flavonoids and have strong antioxidant activities, and rich with phytochemicals (e.g. rutin, quercetin, oleuropein, tyrosol and hydroxytyrosol). Some extracts showed antibacterial activity against both gram positive and negative bacteria as well as antifungal activities and can work, therefore, as preservatives for food or pharmaceutical industries. As an application, two extracts were used as additive to pectin-based packaging film, and results showed that the addition of these extracts significantly improve their functionality as antimicrobial and antioxidant activity. These biomaterials, therefore can be used in food packaging materials to extend the shelf life of food products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plant%20extracts" title="plant extracts">plant extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidants" title=" antioxidants"> antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoids" title=" flavonoids"> flavonoids</a>, <a href="https://publications.waset.org/abstracts/search?q=bioplastic" title=" bioplastic"> bioplastic</a>, <a href="https://publications.waset.org/abstracts/search?q=edible%20biofilm" title=" edible biofilm"> edible biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=packaging%20materials" title=" packaging materials"> packaging materials</a> </p> <a href="https://publications.waset.org/abstracts/168495/plant-extracts-chemical-analysis-investigation-of-antioxidant-antibacterial-and-antifungal-activities-and-their-applications-in-food-packaging-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168495.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">78</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">4037</span> Phytochemical Screening and Evaluation of Antimicrobial and Antioxidant Activity of Anethum graveolens L.

It is cultivated in north -east part of India. It is cultivated in agricultural land by the marginal farmers for multi-storeyed cultivation with intercropping. Localized cottage industries are involved with this plant like sericulture industry (muga silk worm cultivation). Clothes are produced from this sericulture industry. Leaves of som plants are major food of muga silk worm ( Antherea assama ). Nutritional value of leaves plays an important role in the larval growth and silk productivity. The plant also has timber value. The plant is susceptible to mite pest (Tetranychus sp.) causes heavy damage to tender leaves. Lower population was recorded during 7th to 38th standard week, during 3rd week of February to 4th week of September and higher population was during 46th to 51st standard week, during 3rd week of November to 3rd week of December and peak population (6.06/3 leaves) was recorded on 46th standard week that is on 3rd week of November. Correlation studies revealed that mite population had a significant negative correlation with temperature and non-significant positive correlation with relative humidity. This indicates that activity of mites population increase with the rise of relative humidity and decrease with the rise of temperature. Tobacco leaf extracts was found most effective against mite providing 40.51% suppression, closely followed by extracts of Spilanthes (39.06% suppression). Extracts of Garlic and extracts of Polygonum plant gave moderate results, recording about 38.10% and 37.78% mite suppression respectively. The polygonum (Polygonum hydropiper) plant (floral parts), pongamia (Pongamia pinnata) leaves, garlic (Allium sativum), spilanthes (Spilanthes paniculata) (floral parts) were extracted in methanol. Synthetic insecticides contaminate plant leaves with the toxic chemicals. Plant extracts are of biological origin having low or no hazardous effect on health and environment and so can be incorporated in organic cultivation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abiotic%20factors" title="Abiotic factors">Abiotic factors</a>, <a href="https://publications.waset.org/abstracts/search?q=incidence" title=" incidence"> incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=botanical%20extracts" title=" botanical extracts"> botanical extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20cultivation" title=" organic cultivation"> organic cultivation</a>, <a href="https://publications.waset.org/abstracts/search?q=silk%20industry" title=" silk industry"> silk industry</a> </p> <a href="https://publications.waset.org/abstracts/122168/climate-impact-on-spider-mite-tetranychus-sp-koch-infesting-som-plant-leaves-machilus-bombycina-king-and-their-sustainable-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122168.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">139</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">4035</span> Evaluation of South African Plants with Acaricide Activity against Ticks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Fouch%C3%A9">G.

Traditionally, many communities in South Africa rely on a wide range of indigenous practices to keep their livestock healthy. One of these health care practices includes the use of medicinal plants and this offers an alternative to conventional medicine. An investigation was conducted at the CSIR in South Africa, and selected indigenous plants used in communities were scientifically evaluated for the management of ticks in animals. 17 plants were selected from 239 plants used traditionally in South Africa. Two different organic extracts were prepared from the 17 samples, resulting in 34 plant samples. These were tested for efficacy against two tick species, namely <em>Rhipicephalus microplus</em> and <em>Rhipicephalus turanicus. </em>The plant extracts were also screened against Vero cells and most were found to have low cytotoxicity. This study has shown that there is potential for the development of botanicals as natural acaricides against ticks that are non-toxic and environmentally benign. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title="South Africa">South Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=ticks" title=" ticks"> ticks</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20extracts" title=" plant extracts"> plant extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhipicephalus%20%28Boophilus%29%20microplus" title=" Rhipicephalus (Boophilus) microplus"> Rhipicephalus (Boophilus) microplus</a> </p> <a href="https://publications.waset.org/abstracts/71501/evaluation-of-south-african-plants-with-acaricide-activity-against-ticks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71501.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">217</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">4034</span> Influence of Catharanthus roseus, Ocimum sanctum and Lantana camara Extracts on Survival and Longevity of Dysdercus koenigii</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kayesth">Sunil Kayesth</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Kumar%20Gupta"> Kamal Kumar Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of resistance among insects and pests, environmental contamination and adverse effects on non-target organisms is contributed by the indiscriminate use of chemical based insecticides. To overcome these environmental and other ecological issues that are need to replace these harmful toxic compounds. The present study was designed to evaluate the effect of Catharanthus roseus, Ocimum sanctum and Lantana camara plants volatiles on survival and longevity of Dysdercus koenigii. The hexane extract and ethanol extracts of these three plants were used. The fifth instars were exposed to hexane extract with concentrations of 10%, 5%, 2.5% 1.25%, 0.1%, 0.5% 0.25%, 0.125% and 0.0625% while, adults were treated with10%, 5%, 2.5% and 1.25%. 1-ml of each of these concentrations was used to make a thin film in sterilized glass jars of 500 ml capacity. Fifteen- newly emerged fifth instar nymphs and adult bugs were treated separately with the extracts for 24- hour exposure to the plant volatiles. For ethanol extracts cottonseed were treated with ethanol extracts of 10%, 5%, 2.5% and 1.25% concentrations. The treated seeds were provided to the Dysdercus for a period of 24 hours and their feeding behaviour was observed. The effect of hexane and ethanol extract of these plants was observed and readings were recorded for 15 days. Survival and longevity of both fifth instars and adults were in correlation with the concentrations of the plant extracts. Among three plant extracts, Ocimum hexane extract was most toxic and Catharanthus was moderate while Lantana was least toxic. The ethanol extracts of Lantana was highly antifeedent while Ocimum was moderate and Catharanthus was least antifeedent. Both Catharanthus and Ocimum appeared to have potential molecules, which possessed insecticidal activity while Ocimum and Lantana showed antifeedent activities. These insecticidal and antifeedent properties may be used in IPM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catharanthus%20roseus" title="Catharanthus roseus">Catharanthus roseus</a>, <a href="https://publications.waset.org/abstracts/search?q=Ocimum%20sanctum" title=" Ocimum sanctum"> Ocimum sanctum</a>, <a href="https://publications.waset.org/abstracts/search?q=Lantana%20camara" title=" Lantana camara"> Lantana camara</a>, <a href="https://publications.waset.org/abstracts/search?q=Dysdercus%20koenigii" title=" Dysdercus koenigii "> Dysdercus koenigii </a> </p> <a href="https://publications.waset.org/abstracts/39732/influence-of-catharanthus-roseus-ocimum-sanctum-and-lantana-camara-extracts-on-survival-and-longevity-of-dysdercus-koenigii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39732.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">318</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">4033</span> Effect Mechanisms of Aromatic Plants: Effects on Intestinal Health and Broiler Feeding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ozlem%20Durna%20Aydin">Ozlem Durna Aydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Gultekin%20Yildiz"> Gultekin Yildiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antibiotics are microbial metabolites with low molecular weight produced by fungi and algae, inhibiting the development of other microorganisms even in low growth. Antibiotics have been used as growth factors in animal feeds for many years. They prohibited; because of increased residue problem and increased resistance to antibiotics in bacteria due to prolonged use. Aromatic plants and extracts have attracted the attention of scientists nowadays due to positive reasons such as confidence of the community to the products those are coming from nature, desire to consume, and no residue problems. Plant extracts are obtained from aromatic plants, and they come forward with antifungal, antibacterial, antiviral, antioxidant and antilipidemic properties. It has been stated that intestinal histomorphology and microbiosis are positively affected by the use of plant extract in feeds. In the present day, aromatic plants and extracts are a remarkable research field with intriguing unknowns in the field of animal nutrition, and they continue to exist in the journal in vitro and in vivo studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aromatic%20plant" title="aromatic plant">aromatic plant</a>, <a href="https://publications.waset.org/abstracts/search?q=broilers" title=" broilers"> broilers</a>, <a href="https://publications.waset.org/abstracts/search?q=extract%20mechanism%20of%20action" title=" extract mechanism of action"> extract mechanism of action</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20health" title=" intestinal health"> intestinal health</a> </p> <a href="https://publications.waset.org/abstracts/85014/effect-mechanisms-of-aromatic-plants-effects-on-intestinal-health-and-broiler-feeding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85014.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">166</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">4032</span> Phytochemical and Antimicrobial Studies of Root Bark Extracts from Glossonema boveanum (Decne.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Jibrin%20Uttu">Ahmed Jibrin Uttu</a>, <a href="https://publications.waset.org/abstracts/search?q=Maimuna%20Waziri"> Maimuna Waziri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The root bark of Glossonema boveanum (Decne), a member of Apocynaceae family, is used by traditional medicine practitioner to treat urinary and respiratory tract infections, bacteremia, typhoid fever, bacillary dysentery, diarrhea and stomach pain. This present study aims to validate the medicinal claims ascribed to the root bark of the plant. Preliminary phytochemical study of the root bark extracts (n-hexane, ethyl acetate, chloroform and methanol extracts) showed the presence of alkaloids, carbohydrates, steroids, triterpenes, cardiac glycosides, saponins, tannins and flavonoids. Antimicrobial study of the extracts showed activities against Staphylococus aureus, Bacillus subtilis, Salmonella typhii, Shigella dysenteriae, Escherichia coli, Enterobacter cloacae, Streptococcus agalactiae and Candida albicans while Micrococcus luteus, Pseudomonas aeruginosa and Klebsiella Pneumoniae showed resistance to all the extracts. The inhibitory effect was compared with the standard drug ciprofloxacin and fluconazole. MIC and MBC for both extracts were also determined using the tube dilution method. This study concluded that the root bark of G. boveanum, used traditionally as a medicinal plant, has antimicrobial activities against some causative organisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Glossonema%20boveanum%20%28Decne.%29" title="Glossonema boveanum (Decne.)">Glossonema boveanum (Decne.)</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemical" title=" phytochemical"> phytochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title=" antimicrobial"> antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20inhibitory%20concentration" title=" minimum inhibitory concentration"> minimum inhibitory concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20bactericidal%20concentration" title=" minimum bactericidal concentration"> minimum bactericidal concentration</a> </p> <a href="https://publications.waset.org/abstracts/76647/phytochemical-and-antimicrobial-studies-of-root-bark-extracts-from-glossonema-boveanum-decne" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76647.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">268</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">4031</span> Geoclimatic Influences on the Constituents and Antioxidant Activity of Extracts from the Fruit of Arbutus unedo L.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khadidja%20Bouzid">Khadidja Bouzid</a>, <a href="https://publications.waset.org/abstracts/search?q=Fouzia%20Benali%20Toumi"> Fouzia Benali Toumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Bouzouina"> Mohamed Bouzouina </a> </p> <p class="card-text"><strong>Abstract:</strong></p> We made a comparison between the total phenolic content, concentrations of flavonoids and antioxidant activity of four different extracts (butanol, ethyl acetate, chloroform, water) of Arbutus unedo L. fruit (Ericacea) of El Marsa and Terni area.
