Polysaccharide was extracted from Russula Vinosa by hot water extraction technology. Antioxidant activities of Polysaccharide from Russula Vinosa were measured by several experiments,including the Fenton method, the reducing power measure and the Saltzman method of eliminating of NO2- in mimic gastric juice. The antioxidant activities of VC and Russula Vinosa Polysaccharide in vitro were compared at the same concentrations. The result showed that the hydroxyl radicals (·OH) is efficiently eliminated by Russ...
