Abstract：This paper mainly studies the Pleurotus eryngii fungus bran as raw material. Through the high temperature extraction of P.eryngii polysaccharide and preparation process of activated carbon. Through single factor experiment and SAS optimal design, The P.eryngii polysaccharide extraction optimum conditions were as followed: the temperature of 100 ℃，the ratio of material to liquid was 1:10, pH was 7, extraction time was 2.98 hours. The extraction rate of polysaccharide reached 18.13 mg/g, and it increased by 1.6 times before optimization. Microwave carbonization preparation optimum conditions of activated carbon were obtained: 50 % KOH activation 6 hours and 8 min of medium low fire. The adsorption capacity of the activated carbon to menthylene blue was 85.01 mg/g, and the adsorption rate was 97.52 %. This paper provides a theoretic basis and technical support for the resource of P.eryngii.
