Abstract: Lactarius delicious was used as raw material, the material-liquid ratio, microwave power, microwave time, water bath temperature, and water bath time were selected as the variables for the single-factor test, and the Lactarius delicious polysaccharide microwave-assisted extraction process was optimized by using response surface analysis, and its antioxidant activity was studied. The results showed that the best extraction process condition was the material-liquid ratio of 1∶35 g/mL, microwave power of 640 W, microwave time of 25 s, water bath temperature of 90 ℃, and water bath time of 120 min. Under this condition, the extraction rate of polysaccharide from Lactarius delicious was (4.61±0.03)%. The polysaccharide from Lactarius delicious had good antioxidant activity. When the mass concentration of polysaccharide from Lactarius delicious was 1.0 mg/mL, its total reducing ability and DPPH radical scavenging rate reached the maximum.

Key words: Lactarius delicious, microwave-assisted extraction, polysaccharides, antioxidant activity, response surface analysis
