摘　　要：在猪油中添加丹贝异黄酮，观察其对猪油的抗氧化作用。结果发现：添加猪油重量０．０５％的丹贝异黄酮能防止油脂的自动氧化；添加丹贝异黄酮２～１０ｍｇ／ｍＬ对Ｏ－·２的清除率达３７．１１％～９２．８４％；添加０．８～４．０ｍｇ／ｍＬ丹贝异黄酮对·ＯＨ的清除率为３３．８３％～８３．１９％；添加１．０～４．０ｍｇ／ｍＬ丹贝异黄酮对正常小鼠肝匀浆体外脂质过氧化物的生成有抑制作用，抑制率为６７．４０％～７４．２４％。结果表明丹贝异黄酮是一种有效的抗氧化剂和自由基清除剂。Antioxidant effect of isoflavones from tempe(a soybean fermented food) on animal oil was studied. The results showed that 0.05% tempe isoflavones could prevent autooxidation of animal oil; 210 mg/mL tempe isoflavones could scavenge O -· 2 with the rate of 37.11% to 92.84%; 0.84.0 mg/mL tempe isoflavones could scanvenge ·OH with the rate of 33.83% to 83.19%; 14 mg/mL tempe isoflavones could inhibite lipid peroxidation of mice liver homogenate. MDA fromation rate reduced from 67.40% to 74.24%. These results proved tempe isoflavones were an effective antioxidant and active oxygen scanveger.
