摘要: 以1 mmol·L-1油酸孵育HepG2细胞24 h,建立体外高脂模型,在细胞存活率实验(MTT法)的基础上,以脂质清除率为指标,评价茶黄素(TFs)、儿茶素(Cs)和绞股蓝皂苷(SPs)的体外降脂效果;并结合Box-Behnken响应曲面法(RSM)对3种物质体外联合降脂的浓度进行优化。结果表明:茶黄素、儿茶素和绞股蓝皂苷均能清除肝细胞内堆积的脂肪,若三者同时作用,协同效果明显,能起到防治高血脂症的作用。

Abstract: The antihyperlipdemic activity in vitro of theaflavins(TFs), catechins(Cs) and saponius(SPs) were assessed in lipid clearance rate in the model of HepG2 steatosis by using the admini stration with 1 mmol·L-1 oleic acid(OA) in 24 h. Based on the cell viability test(MTT value), lipid clearance was used to evaluate the effect of TFs, Cs and SPs on HepG2 steatosis. The response surface methodology based on a Box-Behnken experimental design was used to optimize the density of the three extractions for combined lipid-lowering in vitro. Results indicated that TFs, Cs and SPs showed a significant inhibitory effect on TG accumulation in HepG2 cells. The ability of lipid-lowering was significant promoted when the three extractions acted on HepG2 at the same time. TFs, Cs and SPs could showed the prevention and curing effect of hyperlipidemia.

Key words: theaflavins, catechins, saponius, in vitro, antihyperlipdemic
