The dried plant of D.scandens was procured from the tirumala. The completely dried powder of the whole plant was taken and ground to a coarse powder which was then subjected to Soxhlet extraction with hexane and chloroform successively for 36 hrs. Chloroform extract was filtered and concentrated by using rotary evaporator an about 100g extract was obtained. The chloroform extract was subjected to column chromatographed over silicagel. From the column chromatography seven compounds were isolated named as osajin, scandinone, scandenone, 4,5,7-tri hydroxy biprenyl isoflavone, derris isoflavone-A, scandenin and isoscandinone. D.scandens resulting in the isolation of seven compounds in the plant was confirmed by spectral data (1H NMR, 13C NMR, ESI-MS and FTIR). The isolated compounds were screened for antioxidant activity, antidiabetic activity, 伪-glucosidase (inhibitory activity) and anti-bacterial activity. The isolated seven compounds were tested for 伪-glucosidase inhibitory activity and antioxidant activity. All the seven compounds showed good 伪-glucosidase inhibitory activity and moderate antioxidant activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Derris%20scandens" title="Derris scandens">Derris scandens</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemical" title=" phytochemical"> phytochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxident" title=" antioxident"> antioxident</a>, <a href="https://publications.waset.org/abstracts/search?q=antidiabetic" title=" antidiabetic"> antidiabetic</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title=" antibacterial activity"> antibacterial activity</a> </p> <a href="https://publications.waset.org/abstracts/59490/phytochemical-and-biological-evaluation-of-derris-scandens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59490.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">316</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">3</span> In vitro Antioxidant Activity of Derris scandens Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nattawit%20Thiapairat">Nattawit Thiapairat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple diseases have been linked to excessive levels of free radicals, which cause tissue or cell damage as a result of oxidative stress. Many plants are sources of high antioxidant activity. Derris scandens has a high amount of phenolic and flavonoid contents which demonstrated good biological activities. This study focused on the antioxidant activity of polyphenols extracted from D. scandens. This study performs total flavonoids content and various antioxidant assays, which were 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging capacity assays. The total flavonoid content of D. scandens extract was determined and expressed as quercetin equivalents (QE)/g measured by the aluminum chloride colorimetric method. The antioxidant activity of D. scandens extract was also determined by DPPH and ABTS assays. In the DPPH assay, vitamin C was used as a positive control, whereas Trolox was used as a positive control in the ABTS assay. The half-maximal inhibitory concentration (IC50) values for D. scandens extract from DPPH and ABTS assays were 41.79 渭g/mL 卤 0.783 and 29.42 渭g/mL 卤 0.890, respectively, in the DPPH assay. To conclude, D. scandens extract consists of a high amount of total phenolic content, which exhibits a significant antioxidant activity. However, further investigation regarding antioxidant activity such as SOD, ROS, and RNS scavenging assays and in vivo experiments should be performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ABTS%20assay" title="ABTS assay">ABTS assay</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=Derris%20scandens" title=" Derris scandens"> Derris scandens</a>, <a href="https://publications.waset.org/abstracts/search?q=DPPH%20assays" title=" DPPH assays"> DPPH assays</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20flavonoid%20content" title=" total flavonoid content"> total flavonoid content</a> </p> <a href="https://publications.waset.org/abstracts/141175/in-vitro-antioxidant-activity-of-derris-scandens-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141175.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">213</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">2</span> Effectiveness of Biopesticide against Insects Pest and Its Quality of Pomelo (Citrus maxima Merr.) </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20Pangnakorn">U.

The selected pomelo was carried out for insects pest control and its quality. The experimental site was located at farmer鈥檚 orchard in Phichit Province, Thailand. This study was undertaken during the drought season (December to March). The extracted from plants and wood vinegar were evaluated in 6 treatments: 1) water as control; 2) wood vinegar; 3) S. tuberosa Lour; 4) T. crispa Mier; 5) D. elliptica Roxb; 6) mixed (wood vinegar + S. tuberosa Lour + T. crispa Mier + D. elliptica Roxb). The experiment was RCB with 6 treatments and 3 replications per treatment. The results showed that T. crispa Mier was the highest effectiveness for reduction population of thrips (Scirtothrips dorsalis Hood) and citrus leaf miner (Phyllocnistis citrella Stainton) at 14.10 and 15.37 respectively, followed by treatment of mixed, D. elliptica Roxb, S. tuberosa Lour and wood vinegar with significance different. Additionally, T. crispa Mier promoted the high quality of harvested pomelo in term of thickness of skin at 12.45 mm and S. tuberosa Lour gave the high quality of the pomelo in term of firmness (276.5 kg/cm2) and brix (11.0%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20vinegar" title="wood vinegar">wood vinegar</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title=" medicinal plants"> medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=Pomelo%20%28Citrus%20maxima%20Merr.%29" title=" Pomelo (Citrus maxima Merr.)"> Pomelo (Citrus maxima Merr.)</a>, <a href="https://publications.waset.org/abstracts/search?q=Thrips%20%28Scirtothrips%20dorsalis%20Hood%29" title=" Thrips (Scirtothrips dorsalis Hood)"> Thrips (Scirtothrips dorsalis Hood)</a>, <a href="https://publications.waset.org/abstracts/search?q=citrus%20leaf%20miner%20%28Phyllocnistis%20citrella%20Stainton%29" title=" citrus leaf miner (Phyllocnistis citrella Stainton) "> citrus leaf miner (Phyllocnistis citrella Stainton) </a> </p> <a href="https://publications.waset.org/abstracts/26281/effectiveness-of-biopesticide-against-insects-pest-and-its-quality-of-pomelo-citrus-maxima-merr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26281.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">373</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">1</span> Taxonomy of Araceous Plants on Limestone Mountains in Lop Buri and Saraburi Provinces, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duangchai%20Sookchaloem">Duangchai Sookchaloem</a>, <a href="https://publications.waset.org/abstracts/search?q=Sutida%20Maneeanakekul"> Sutida Maneeanakekul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Araceous plant or Araceae is a monocotyledon family having numerous potential useful plants. Two hundred and ten species of Araceae were reported in Thailand, of which 43 species were reported as threatened plants. Fifty percent of endemic status and rare status plants were recorded in limestone areas. Currently, these areas are seriously threatened by land-use changes. The study on taxonomy of Araceous plants was carried out in Lop Buri and Saraburi limestone mountains from February 2011 to May 2015. The purposes of this study were to study species diversity, taxonomic character and ecological habitat. 55 specimens collected from various limestone areas including Pra Phut Tabat National forest (Pra Phut Tabat Mountain, Khao Pra Phut Tabat Noi Mountains, Wat Thum Krabog Mountain), Tab Khwang and Muak Lek Natinal forest (Pha Lad mountain, and Muak Lek waterfall) in Saraburi province ,and Wang Plaeng Ta Muang and Lumnarai National forest (Wat Thum chang phuk mountain), Panead National forest (Wat Khao Samo Khon Mountain), Lan Ta Ridge National forest (Khao Wong Prachan mountain, Wat Pa Chumchon) in Lop Buri province. Twenty species of Araceous plants were identified using characteristics of underground stem, phyllotaxis and leaf blade, spathe and spadix. Species list are Aglaonema cochinchinense, A. simplex, Alocasia acuminata, Amorphophallus paeoniifolius, A. albispathus, A. saraburiensis, A. pseudoharmandii, Pycnospatha arietina, Hapaline kerri, Lasia spinosa, Pothos scandens, Typhonium laoticum, T. orbifolium, T. saraburiense, T. trilobatum, T. sp.1, T. sp. 2, Cryptocoryne crispatula var. balansae, Scindapsus sp., and Rhaphidophora peepla. Five species are new locality records. One species (Typhonium sp.1) is considered as a new species. Seven species were reported as threatened plants in Thailand Red Data Book. Taxonomic features were used for key to species constructions. Araceous specimens were found in mixed deciduous forests, dry evergreen forests with 50-470 m. elevation. New ecological habitat of Typhonium laoticum, T. orbifolium, and T. saraburiense were reported in this study. <p class="card-text"><strong>Keywords:</strong> <a
