摘  要:
通过邻苯三酚自氧化法,水杨酸比色法分别测定了华木莲叶黄酮类化合物(Sinomanglietia glaulaLeaf F la-vonoids,SLF)清除超氧阴离子自由基(O2.)、羟基自由基(.OH)的效果,及其对H2O2诱导的大鼠血红细胞溶血作用的影响来研究SLF的抗氧化性作用。结果表明:不同浓度的SLF均能显著地清除超氧阴离子自由基(O2.)、羟基自由基(.OH),抑制H2O2对红细胞膜的破坏而引起的溶血,抗氧化性作用随SLF浓度的升高而增强。

摘  要:
The flavonoid is a macromolecular organic compound, which is widely used in food and medicine industry.In this paper,the anti-oxidation effect of flavonoids extracted from Sinomanglietia glaula leaf is studied in the following way: scavenging superoxide anion free radical(O~·_2) and hydroxyl free radical((·OH)) by progallol autoxidation and salicylic acid colorimetry respectively,and inhibiting rats' RBC hemolysis induced by H_2O_2.The results show: Sinomanglietia glaula Leaf Flavonoids(SLF) can scavenge superoxide anion free radical(O~·_2) and hydroxyl free radical(·OH) effectively,and inhibit RBC hemolysis remarkably.Moreover,the anti-oxidation effect strengthens with the increase of SLF density.
