摘要
采用了Fe2+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(RhododendronsimsiiPlanch.)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(RhododendronL.)植物的花蕾抗氧化活性最强。一定浓度白杜鹃〔R.mucronatum(Blume)G.Don〕花蕾提取液的抗Fe2+诱发的脂蛋白PUFA过氧化活性明显高于维生素C。
<Abstrcat> 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.
