%X The antioxidant activities in vitro of polysaccharides from Cantharellus cibarius, Russula virescens, Tricholoma myomyces and Armillaria mellea were evaluated by testing their DPPH radical scavenging activities, hydroxyl free radical scavenging activities, ferrous ion chelating ability and reducing activity. The results showed that the crude polysaccharides from T. myomyces and A. mellea had the most potent capacity for scavenging DPPH with EC50 values reaching 1.35 g/L and 1.53 g/L, and they were superior to the other two fungi in the scavenging hydroxyl radical capacity, with EC50 values reaching 0.65 g/L and 0.78 g/L, respectively. The polysaccharide from T. myomyces showed the most potent ferrous ion chelating ability with EC50 values reaching 1.69 g/L. In respect to the potent capacity for reducing power, the polysaccharide from T. myomyces showed the most potent capacity with EC50 values reaching 1.05 g/L, followed by that of A. mellea with EC50 values reaching 1.37 g/L.
