Research ArticleOpen accessEvery word in the titleOptimization of Ultrasonic/Microwave Assisted Extraction (UMAE) and Rheological Properties of Polysaccharides from Auricularia polytrichaZe Zhang, Xiao Ding, Ziyi Xu et al.Polysaccharides from Auricularia polytricha (APPS) were extracted using Ultrasonic/Microwave Assisted Extraction (UMAE) technology. UMAE conditions of APPS were optimized with Response Surface Methodology (RSM). Rheological properties of APPS were investigated. The results suggested that the optimal UMAE conditions for APPS were ratio of water to raw material 22 (mL/g), extraction time 15.3 min and microwave power 59W. APPS solution exhibited … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 14 Mar 2020 · 7,420 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization, Characterization and Antioxidant Activities of Selenized Polysaccharides from Hypsizygus marmoreusTing Liu, Xue Jiang, Wei Wang, Bing XuIn this study, hypsizygus marmoreus was used as raw material to extract polysaccharides by hot water extraction method. Preparation technology of Selenized Polysaccharides from Hypsizygus marmoreus (SPHM) and its antioxidant activities were investigated. Chelation rate was selected as the index, effects of initial concentration of sodium selenite (mg/mL), the mass ratio of polysaccharide to sodium selenite, chelation time and pH … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 8 Aug 2019 · 7,774 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFrom Hyperthermia to Immunomodulating PolysaccharidesNovak Miroslav, Vetvicka VaclavNatural polysaccharides remain overlooked as part of naturally occurring bioactive molecules. The current knowledge results in numerous clinical trials, from first observations of their effects on various diseases to precise chemical characterization and decades of biological evaluation.
