【 摘 要 】

In the present study, the sulphated derivative (S-CBP) with the degree of substitution (0.46) was successfully prepared from the polysaccharide extracted from corn bran. Compared with native polysaccharide, the structures of the sulphated derivative were confirmed by FT-IR and SEC-LLS and the molecular weight were changed by chemical modification. Sulfation enhanced the antioxidant activities in a dose-dependent way, which seemed to be dependent on the character of the substituted group. The results suggest that the sulphated derivative, extracted from corn bran, are potential natural antioxidant and blood fat reduce agent.
