主 题：Ginseng polysaccharides graded ethanol precipitation physicochemical property antioxidant activity
摘 要：Ginseng polysaccharides were extracted by water decoction from Panax ginseng ***(Cultivated Ginseng),named *** polysaccharide fractions,CGPS-20,CGPS-40,CGPS-60 and CGPS-80,were precipitated at final ethanol concentrations of 20%,40%,60%and 80%,*** properties,molecular weight,monosaccharide composition and antioxidant capacity of polysaccharide fractions were all *** results indicated that changing the concentration of ethanol could precipitate polysaccharides into fractions with different molecular weights,functional group composition and physicochemical properties,eventually leading to differences in antioxidant activity,which would help to find a simple,efficient,and reliable method for rapid extraction and purification of antioxidant polysaccharides from Panax ginseng *** the four polysaccharide fractions,CGPS-80 had lower molecular weight,higher contents of uronic acid and total phenolic,and stronger scavenging ability on DPPH∙and ABTS∙+radicals.
