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 · 7,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction, Partial Identification and Bioactivities of Total Flavonoids from Carex meyeriana KunthHongbiao Wang, Penghui Wang, Xiudong Yang et al.To date, knowledge associated with extraction, chemical constituents and bioactivities of Total Flavonoids from Carex meyeriana Kunth (TFCMK) that remains unclear. Therefore, this paper was designed to optimize the ethanol reflux extraction method by response surface methodology and determine the chemical constituents by Liquid Phase-Mass Spectrometry (HPLC-MS); additionally, the bioactivities including antioxidant, antibacterial and hemolysis test were also explored. The … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 7 Aug 2019 · 7,525 accessesView PDFCite
