Ultrasonic-assisted extraction method was used to polysaccharides from Atractylodes macrocephala, and the orthogonal test was applied to optimize extraction conditions. Furthermore ,the antioxidant activities of Atractylodes macrocephala polysaccharides were evaluated by DPPH and superoxide anion radical scavengingactivities assay. The results indicated that the optimal conditions for Atractylodes macrocephala polysaccharides extraction as followings:solid/liquid ratios of 1 : 20 (g/mL), extraction time of 40 min, ultrasonic power of 65 W and extractiontemperature of 55 ℃ . Meanwhile,Atractylodes macrocephala polysaccharides had relatively higher scavenging activities on DPPH and superoxide anion radicals.
