Research ArticleOpen accessIn the abstractGreen Synthesis of Silver Nanoparticles using Extract of Disporopsis Longifolia for Photocatalytic Degradation of Methylene BlueKhieu Thi Tam, Dang Van Thanh, Huu Tap Van et al.In this report, the silver Nanoparticles (AgNPs)were successfully synthesized in a simple one-pot method by the leaf and stemextract of Disporopsis longifolia as reducing, capping agents, andstabilizers for the first time. The optimal extract amount, AgNO3concentration, reaction temperature, and time for the AgNPs synthesis wereidentified using Ultraviolet-Visible (UV-Vis) spectroscopy. X-Ray Diffraction (XRD)and Scanning Electron Microscopy (SEM) were used to characterize … …American Journal of Environmental Sciences, Vol. 18, Issue 5 · 23 Nov 2022 · 6,563 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcer Buergerianumas a New Resource for the Extraction of Corilagin: Determination of Corilaginin Different Cultivars of A. Buergerianumby UPLCQian Qiao, Chong Wu, Jiangyong Wang et al.Corilagin is a promising anticancer drug candidate. Acer nikoense and A. ammonium are both known to contain corilagin. To explore whether corilagin occurs in congeneric species and to fully develop the medicinal value of maple, the corilagin content in different varieties of maple was determined by Ultrahigh-Performance Liquid Chromatography (UPLC). Acer buergerianum leaves contained corilagin and the corilagin content in … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 2 · 12 May 2022 · 5,704 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro Digestibility of Hay Mangrove with Native GrassRani Winardi Wulan Sari, Novirman Jamarun, Suyitman et al.Forage is the main component of feed given to ruminants. Local feed ingredients that can be used are mangroves and native grass. This study used the Randomized Block Design (RBD) experimental method with 4 = four treatments and 5-five replications. The treatments composed of Hay Mangrove Leaves and Native grass as follows: A (60 + 40%), B (50 + 50%), … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 4 · 19 Dec 2022 · 5,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbiotic Stress Elicitation on Secondary Metabolites of Red Betel (Piper crocatum Ruiz and Pav.) Leaves as Potential Repellent for Rice Bug (Leptocorisa oratorius (F.)Intani Quarta Lailaty, Diah Rachmawati, Laurentius Hartanto NugrohoRice bug, Leptocorisa oratorius (F.), is the main pest of rice plants which can reduce rice productivity significantly. Natural insecticide from plant extract compounds, such as Red Betel (Piper crocatum Ruiz and Pav.), is an alternative to reduce the attack of these pests and environmental friendly. This research aimed to study the effect of abiotic stress on plant growth and … …OnLine Journal of Biological Sciences, Vol. 21, Issue 1 · 23 Jan 2021 · 7,495 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization for the Extraction of Polysaccharide from Walnut (Juglans regia L.) Leaves: Antioxidant Activities in VitroShuqing Yang, Haifang Xiao, Shuyan Yu et al.Cellulase-assisted extraction of Walnut Leaf Polysaccharide (WLP) was studied. Single factor test and response surface design were employed to optimize the technological conditions. The consequences indicated that the highest WLP yield of 5.21% was achieved with raw material ratio of 50 mL/g, cellulase dose of 41488.52 U/g, enzymolysis pH of 5.88, enzymolysis time of 29.74 min and enzymolysis temperature of … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 23 Oct 2019 · 7,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of 1-Deoxynojirimycin Content and Phytochemical Profiles from Young and Mature Mulberry Leaves of Morus Spp.Yasinta Ratna Esti Wulandari, Vivitri Dewi Prasasty, Adrianus Rio, Cindy GeniolaMulberry leaves have been known to be rich in 1-Deoxynojirimycin (DNJ) which inhibits postprandial hyperglycemia by inhibiting α-glucosidase in the small intestine and thereby reducing the breakdown of starch and other complex sugar into glucose. Mulberry leaf extract also contains many other bioactive compounds and phytochemicals. They are very effective in supporting blood sugar levels and balancing cholesterol and triglycerides. … …OnLine Journal of Biological Sciences, Vol. 19, Issue 2 · 3 Jun 2019 · 11,074 accessesView PDFCite
