Abstract: Edible fungi [Hericium erinaceus (Bull.) Per.,Pleurotus eryngii Quel.,Lentinus edodes(Berk.) Sing.,Pleurotus ostreatus]were fermented to obtain mycelium. Polysaccharide were extracted from the mycelium and determined the DPPH free radical scavenging and reducing power of the four polysaccharides. Four kinds of polysaccharide were mixed in different proportions(respectively programme 1∶Hericium erinaceus(Bull.) Per.∶Pleurotus ostreatusLentinus edodes(Berk.) Sing.∶Pleurotus eryngii Quel.=1∶1∶1∶1,programme 2∶Hericium erinaceus(Bull.) Per.∶Pleurotus ostreatusLentinus edodes(Berk.) Sing.∶Pleurotus eryngii Quel.=4∶3∶2∶1,programme 3∶Hericium erinaceus(Bull.) Per.∶Pleurotus ostreatusLentinus edodes(Berk.) Sing.∶Pleurotus eryngii Quel.=5∶4∶3∶2),and study the antioxidant activity of compound polysaccharide. The results showed that the four kinds of mycelial polysaccharides have certain reduction capacity and the ability of scavenging DPPH free radical. Among them,the antioxidant activity of Hericium erinaceus polysaccharide was the highest. The results showed that the antioxidant activity from programme 2 was the best, and was significantly higher than that of single polysaccharide.
