Abstract

Crude polysaccharide was isolated from the stem of Sedum aizoon L. Antioxidant activity of crude polysaccharide was evaluated with 2, 20-diphenyl-l-picrylhydrazyl (DPPH), 2, 20-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), superoxide radical scavenging, hydroxyl radical scavenging and reducibility. It exhibited a powerful ABTS radical and hydroxyl radical scavenging character when compared with the standard Vitamin C. However, the antioxidant test indicated that crude polysaccharide had no significant effect on DPPH.

 

Key words: Sedum aizoon L., antioxidant activity, polysaccharide.
