摘　　要：通过二色胡枝子黄酮(Lespedeza bicolor flavonoids,LBF)清除羟自由基、超氧阴离子的效果及抑制猪油、菜油、和亚油酸的自氧化来研究二色胡枝子黄酮的抗氧化活性。其研究结果表明,二色胡枝子黄酮对清除自由基有显著性作用,且清除率随黄酮浓度的增加而增大;能够极显著地抑制猪油、菜油、亚油酸的自氧化(P<0.01),抑制作用随浓度的增大而增强。作为天然的抗氧化剂,二色胡枝子黄酮具有一定的开发利用价值。Antioxidative activity of flavonoids from Lespedeza bicolor （LBF） were investigated by examining the scavenging effects on hydroxyl radicals （ ·OH） and superoxide anion（O2^-） and the inhibitions on auto-oxidation of lard, rape seed oil, and linoleic acid, The results showed that LBF had significant scavenging functions to free radical and superoxide anion, and the scavenging effect increased with the increase of the content of LBF; LBF can remarkably inhibit auto-oxidation of lard, rape seed oil, and linoleic acid, indicating its potential as a natural antioxidant.
