The pleurotus eryngii polysaccharide was extracted through using cellulase as subsidiary condition. The optimized conditions were studied by one-factor experiment and orthogonal experiment. The result showed that the influential degree weakened as follows sequence: pH, enzyme quantity, time and temperature. The suitable condition for extraction of pleurotus eryngii polysaccharide was enzyme quantity 0.030%, pH 4.5, temperature 55℃, and 40 minutes with 5 g of pleurotus eryngii in 100 mL enzyme suspension. Under optimized condition, the pleurotus eryngii polysaccharide yield was 27.0 mg/Kg.
