摘要: 用水杨酸法研究连翘叶茶提取物(FSE)清除•OH的效果,用硫代巴比妥酸法测定小鼠组织及肝线粒体、微粒体中丙二醛含量,用分光光度法测定小鼠红细胞溶血和肝线粒体膨胀程度研究FSE的抗氧化效果。结果表明:FSE可以清除•OH,抑制•OH所致丙二醛的产生,减少红细胞溶血,减轻肝线粒体膨胀程度。可以得出FSE具有明显的抗氧化的作用。

Abstract: The scavenging effect of FSE(extracts of Forsythia leaves infusion tea)on hydroxyl radicals(•OH)was studied by salicylic acid method.To study the anti-oxidative effect of FSE,the contents of MDA in tissue and mitochondria and microsome of liver were measured by TBA assay,and the hemolysis extent of red blood cells and the swelling extent of mitochondria of liver were also detected by spectrophotometric methods.The result showed that FSE had the•OH scavenging activity.It could inhibit the generation of MDA,the swelling of mitochondria,and the hemolysis of red blood cells.The conclusion was that FSE had the effect of anti-oxidation.
