Abstract:
Taking bayberry leaf as material,the ultrasonic assisted extraction technology of bayberry leaf crude polysaccharide optimum extraction conditions and bayberry leaf antioxidant activity of polysaccharide were studied.The results showed that the ultrasonic assisted extraction of the better programs bayberry leaves polysaccharide;ultrasonic power was 250 W,ultrasonic time was 20 min,ultrasonic temperature was 65℃,the solid to liquid ratio was 1∶60 g/mL；the ultrasonic temperature had the greatest influence on extraction rate.In addition,the of bayberry leaves in the polysaccharide OH and O2 had significant scavenging effect,the reduction ability,bayberry leaves polysaccharides had antioxidant activity.
