Abstract: In this paper, the polysaccharides of Pleurotus ostreatus were extracted by enzymy and hot-water, and precipitated with perpendicular experiments. The protein in polysaccharides was removed by sevage way. The polysaccarides were graded to A、B、C、D by ethnol. The results showed that the extracting rate of water soluble polysaccharides by enzyme was 15. 7%, and the polysaccharides had antioxidation effect on the• OH and O•2.

Key words: Pleurotrs ostreatus, water soluble polysaccharides, structure, antioxidation
