摘要: 建立三个活性氧模型研究贻贝对氧自由基和脂质过氧化的作用。结果表明,贻贝匀浆液具有清除O2■、·OH和抑制脂质过氧化作用,其IC50分别为7.65±0.33mg、14.30±1.15mg、30.60±2.19mg;经不同处理得到的样品对三个系统的抑制程度有所不同。

Abstract: Three oxygen free radical generation models were established to study the effects of Mytilus edulis on scavenging oxgen free radical and inhibiting lipid peroxidation. The results Showed that the hemogenated liquid of Mytilus edulis could scaveng superoxide radical and hydroxyl radical and inhibit lipid peroxidation. the values of IC50 were as follows: 7.65± 0.33mg、14.30±1.15 mg. 30.60±2. 19 mg. Inhibition level of the different samples disposed to the three systems was different.
