Antioxidant Activity of Polysaccharide from Dictyophora rubrovalvata

In this paper,the antioxidant activity of polysaccharides from Dictyophora rubrovalvata was investigated by using DPPH,hydroxyl radical and superoxide radical assay systems,with VC and BHT as positive control.The results showed that the polysaccharides possessed moderate scavenging activity on DPPH,hydroxyl radical and superoxide radical with EC50 values of 1.468,2.580 and 2.3304,respectively,and its antioxidant activity was higher than BHT but lower than VC.
