| 摘 要： | 采用了Fe^2 诱发的脂蛋白PUFA过氧化、H2O2诱导的RBC溶血和紫外线（UV）诱发的RBC溶血等3个体外抗氧化实验体系，对映山红（Rhododendron simsii Planch.)等35种鲜花的抗氧化活性进行了测定和比较。结果表明，在所测定的35种鲜花中，4种杜鹃属（Rhododendron L.)植物的花勒抗氧化活性最强。一定浓度白杜鹃[R.mucronatum (Blume)G.Don]花蕾提取液的抗Fe^2 诱发的脂蛋白PUFA过氧化活性明显高于维生素C。

| Abstract: | Antioxidant activities of 35 kinds of fresh flowers were determined and compared by three %in vitro %antioxidants screening systems (including: lipoprotein PUFA peroxidation system induced by Fe+{2+}, hemolysis system induced by H-{2}O-{2} and ultraviolet|induced hemolysis system). The results indicated that buds of 4 species of %Rhododendron %L. showed the most efficient antioxidant activities in all samples. The anti|lipidperoxidation activity of certain concentration extracts from %R. mucronatum %(Blume) G. Don bud is higher than that of Vc. |
