The results show that the scope of the pilot, Sinonovacula constricta polysaccharide on hydroxyl radical (·OH) and superoxide anion radical (·02一) has a strong scavenging, scavenging capacity with the polysaccharide concentration increases , Sinonovacula constricta Polysaccharides inhibited lipid peroxide formation, this inhibition has a dose-effect relationship, in the razor clam polysaccharide concentration of 6 mg / mL when, LPO clearance rate could reach 63.72%; also found Sinonovacula constricta polysaccharide has good inhibiting oxidative damage, protect the function of erythrocyte membrane.4 The composition and structure of LPS-ITLC, IR, HPLC and GC were used for structure analysis.

结果:缢蛏多糖对羟自由基(·OH)和超氧阴离子自由基(·02一)具有较强的清除作用,清除能力随多糖浓度的增大而增大;缢蛏多糖可抑制脂质过氧化物的生成,此抑制作用具有一定的量效关系,在缢蛏多糖浓度为6 mg/mL时,LPO清除率可达到63.72%;此外还发现缢蛏多糖具有较好的抑制氧化损伤,保护红细胞膜的功能。
