摘要:

以α- 生育酚作为对照,研究茶多酚、没食子酸、槲皮素、山奈素、芹菜素五种多酚化合物对H2O2 和CCl4 诱导的人肝细胞损伤的保护作用。结果表明,不同浓度的多酚化合物(5、10、20 mg/L)与肝细胞预先作用1h,再进行诱导损伤,可以提高肝细胞的细胞活率和还原型谷胱甘肽(GSH)含量水平,降低乳酸脱氢酶(LDH)渗出率和丙二醛(MDA)生成量。显示它们对H2O2 和CCl4 诱导的肝细胞损伤有保护作用,保护能力大小顺序为没食子酸>槲皮素>茶多酚>芹菜素>α- 生育酚>山奈素。其保护作用可能与多酚化合物具有较强的清除自由基能力有关。

Abstract:

The potential hepatoprotective effects of five polyphenols, such as tea polyphenol, gallic acid, quercetin, kaempferol, apigenin and α-tocopherol (as a control) against oxidation damages of human hepatocyte induced by hydrogen peroxide or carbon tetrachloride were evaluated. The results showed that pre-treatment of hepatocytes with polyphenols at concentrations of 5, 10 and 20 mg/L for 1 h not only improve cell viability and the content of GSH, but also reduce LDH leakage and the formation of MDA in cells. The hepatoprotective effects of polyphenol compounds decrease in the following order: gallic acid > quercetin > tea polyphenol > apigenin > α-tocopherol > kaempferol. The protective mechanism may be associated with the high free radicalscavenging activity of polyphenlos.
