Objective:Polysaccharides of Quisqualp indica was extracted by using the method of ultrason-ic. And study on the antioxidant of the polysaccharides . Method:Polysaccharide of Quisqualp indica ex-traction influence effect was researched by the solid-liquid ratio, ultrasonic action time,ultrasonic temper-ature, and ultrasonic power. Measure clearance ability of the extracts on ·OH and ·O -2 . to evaluate its antioxidant activity. Results:The best condition of ultrasonic extraction were solid-liquid ratio1 ∶ 30 (g /mL),temperature 70 ℃,ultrasonic power 140 W and ultrasonic action time 50 min. The extraction ratio of polysaccharides was 10. 36% . Experiments showed that polysaccharide from Quisqualp indica had great effect on clearance of ·OH and ·O -2 . Conclusion:Polysaccharide of Quisqualp indica had strong antiox-idant activity. It provided scientific basis for the use of Quisqualp indica and development.
