  ABSTRACT: The polysaccharides were extracted by different power ultrasound from Ophiopogon japonicas. The extraction yield and in vitro antioxidant activities including scavenging effect on hydroxyl radical, superoxide anion free radicals and DPPH were investigated. The results showed that with the increase of ultrasonic power, the yield of the polysaccharides decreased first and then increased. The antioxidant activity of polysaccharides increased first and then decreased with the increase of ultrasonic power. When the power was 400 W, the scavenging effect on superoxide anion and DPPH of the polysaccharides was the strongest, and the scavenging ability of hydroxyl radical was the strongest when the power was 560 W. Therefore, different ultrasonic power could affect the extraction yield and antioxidant activity of Ophiopogon japonicas polysaccharide. It will provide theoretical basis and experimental support for the application of ultrasonic extraction on polysaccharides from Ophiopogon japonicas.
