摘　　要：为了探讨番红花花瓣总黄酮的体外抗氧化作用,采用分光光度法测定其对血清羟自由基、脂质过氧化物(MDA)、NO及超氧阴离子等的清除能力,并通过多元线性回归分析,考察番红花花瓣总黄酮与体外抗氧化活性的相关性。结果表明,番红花花瓣总黄酮具有较强的抗氧化性能、自由基清除能力和一定的还原力,能有效抑制脂质过氧化,且抗氧化能力与番红花花瓣总黄酮含量呈正相关。To study antioxidant activity of flavonoids from Crocus sativus petals in vitro, the study tested the clearance capacity of flavonoids on hydroxyl free radicals, lipid per oxidation in serum （MDA）, NO and superoxidc anion by spectrophotometers. And by multivariate linear regression analysis, relevance of total flavonoids in C. sativus petals and antioxidant activity in vitro was studied. Results showed that flavonoids in C. sativus petals had strong antioxidant, free radical scavenging capacity and some restorative power. It could effectively inhibit lipid peroxidation, and antioxidative capacity were related with total flavonoids content.
