Wang, Li published the artcilePhysicochemical properties and bioactivities of original and Se-enriched polysaccharides with different molecular weights extracted from Pleurotus ostreatus, SDS of cas: 59-23-4, the main research area is pleurotus selenium polysaccharide mol weight bioactivity physicochem property; Antioxidant activity; Different molecular weight; Hypoglycemic activity; Pleurotus ostreatus; Selenium polysaccharides.
Three polysaccharides (WZP1, WZP2, WZP3) and their Se-enriched products (SeWZP1, SeWZP2 and SeWZP3) were obtained from Pleurotus ostreatus using a simple, rapid method and HNO3-Na2SeO3 method, resp. The mol. weight distribution profiles of all samples except SeWZP2 showed double peaks. The average mol. weights (Mw) of WZP1-3 were 48.6 kDa, 20.2 kDa and 11.8 kDa, resp., and of SeWZP1-3 were 19.6 kDa, 37.7 kDa, 14.5 kDa, resp. The complexity of monosaccharide composition of WZP1-3 was inversely proportional to the ethanol concentration used in the ethanol precipitation process. Addnl., the results of biol. activity tests indicated that a-glucosidase inhibitory activity of WZP1-3 was related to the mol. weight and the monosaccharide composition complexity. The selenized modification can improve the a-glucosidase-inhibiting, hydroxyl radical-scavenging activity of P. ostreatus polysaccharides. Therefore, by improving their bioactivities by selenization, the polysaccharides of P. ostreatus could be utilized as a natural health food supplement.
