dry goods and also identified each polysaccharide content with the anthronesulfuric acid method. The selected dry goods as medlar, agrocybe cylindracea and lily all have inoxidizability in different antioxidant systems. There are some doseeffect relationships between the concentration of polysaccharide and its antioxidant capacity. Under the same concentration conditions, pared with Vitamin C, it can be obtained that the antioxidant capacity of agrocybe cylindracea is better than that of Vitamin C, the antioxidant capacity of lily is almost the same as Vitamin C, and the antioxidant capacity of medlar is worse than that of Vitamin C.
