Abstract:
Heritiera littoralis shell was used as materials，the process conditions of using alcohol water bath method to extract Heritiera littoralis shell polysaccharide was studied by single factor test and response surface analysis，as well as the scavenging effect of Heritiera littoralis shell polysaccharide on DPPH? and hydroxyl radical were studied.The results showed the optimal extracting conditions were as follows,extracting temperature 72 ℃，extracting time 53 minutes，liquid-solid ratio 64∶1 mL?g-1,extracting twice.Under such conditions，the extraction ratio of Heritiera littoralis shell polysaccharide was 14.01%.Scavenging effect of Heritiera littoralis shell polysaccharide on DPPH? and hydroxyl radical were obvious，which appeared linear.It showed that the antioxidation activity of Heritiera littoralis shell polysaccharide appeared well.
