Study on the Functional Activity of Pineapple Polysaccharide in vitro
摘要
Abstract
Pineapple polysaccharide was extracted from pineapple peel to discuss the antioxidant function of polysaccharide pineapple in vitro.Hot water extraction was used to extract polysaccharide pineapple.The ability of pineapple polysaccharide to scavenge free radicals was studied by using hydroxyl radicals system,superoxide anion system and polysaccharide reductive ability system.Results showed that,using salicylic acid colorimetry to determine the ability of pineapple polysaccharide to scavenge hydroxyl radicals,when the concentration was 12 mg/mL,the scavenge rate reached 90%.While using pyrogallol autoxidation method to determine the ability of pineapple polysaccharide to scavenge the superoxide anion,when the concentration was 6 mg/mL,the clearance of super oxide anion reaches 80%.The reductive ability of pineapple polysaccharide was enhanced with its concentration was increased,and there was a good concentration-response relationship between the concentration and reductive ability.关键词
