摘要: Phosphorylated modification of a polysaccharide obtained from Radix Hedysari (RHP) was studied. Three phosphorylated polysaccharides (RHPP) with variable degrees substitution (DSp) were 4-dimethylaminopyridine (DMAP) and N, N′ Dicyclocarbodiimide (DCC) as catalyst. The structures RHPP characterized by FT-IR spectra 13C NMR spectra. Depending on different reaction time, showed DSp ranging 0.30 to 0.66, Mw 86.6 89.7 KDa. Compared RHP, exhibited superior antioxidant activities in vitro, which indicated that could enhance RHP. Furthermore, it obvious the had significant effect activity.
