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 Fe^{2 +}诱发的脂蛋白 PUFA 过氧化活性明显高于维生素 C。
 

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 H2 O2 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 antilipidperoxidation activity of certain concentration extracts from R .mucronatum (Blume)G .Don bud is higher than that of Vc.
