Abstract

Abstract: A polysaccharide SCP-B II was obtained from Schisandra chinensis Turcz.Bail.fruits by method of water extraction and ethanol precipitation for protein removal. After DEAE-Cellulose 52 and Sephadex G-200 column chromatography, single component SCP-B II was got. The scavenging ability of ·OH and O·2 of SCP-B II were assayed by chemiluminescence. The results showed that SCP-B II have evident abilities of scavenging ·OH and O·2.

Key words: Schisandra chinensis polysaccharides, purification, scavenging free radical
