摘要
为进一步探明茶多酚复合物祛病延衰作用的机理,实验观察了绿茶提取物——绿茶多酚类复合物(GTPP)对小鼠体内外脂质过氧化的影响. 结果表明:GTPP在体外能抑制正常小鼠肝、脑和心肌匀浆过氧化脂质(LPO)的生成;小鼠口服一定剂量的GTPP能明显抑制肝、脑、心肌组织和血清中LPO的生成,同时能降低小鼠大脑皮层、心肌、肝和肾组织细胞脂褐素(LF)的含量.实验表明:GTPP可维持体内自由基的动态平衡。
The effect of green tea polyphenols (GTPP) on lipid peroxidation was observed.The results showed that GTPP could inhibit the production of lipid peroxides (LPO) in the liver, brain and heart of the rat. After administering GTPP at the doses of 40, 80 and 100 mg/(kg·d) -1 for 15 days, the LPO and lipofucin levels were greatly reduced compared with the levels of the control group, which suggested that green tea polyphenols could inhibit LPO and maintain the bacance of the free radicals in vivo.
