摘要: 目的:研究滇西33 种菊科植物的体外降脂活性,为发现植物来源的新型降脂天然产物奠定基础。方法:利用75%乙醇对33 种菊科植物进行回流提取,采用人肝癌细胞HepG2 高脂模型测定各植物提取物的体外降脂活性,以降脂率对其活性结果进行评价。结果:24种菊科植物提取物具有不同程度的体外降脂活性,其中熊胆草、紫茎泽兰、狼杷草及肿柄菊提取物体外降脂活性显著,终浓度为0.5 mg/mL 时,降脂率分别为(18.4±1.9)%、(18.4±9.7)%、(17.5±10.2)%、(15.1±13.4)%,此4 种菊科植物提取物与辛伐他汀体外降脂率比较,差异均有统计学意义(P<0.01)。结论:熊胆草、紫茎泽兰、狼杷草、肿柄菊4 种植物具有显著的体外降脂活性,值得后续深入研究。

Abstract: Objective:To determine the in vitro lipid-lowering activity of 33 Compositae plants from West Yunnan,and to provide
a scientific basis for the discovery of novel hypolipidemic drugs from plants. Methods:33 Compositae plants were extracted by reflux
method with 75% ethanol. A high-lipid model of HepG2 cells was used to determine the lipid-lowering activities of plant extracts in
vitro. And the lipid-lowering rate was used to evaluate the activity. Results:24 Compositae plant extracts exhibited in vitro lipidlowering
activity in different degrees. The Conyza blinii,Ageratina adenophora,Bidens tripartita,Tithonia diversifolia showed
significant in vitro lipid-lowering activities with lipid-lowering rates of(18.4±1.9)%,(18.4±9.7)%,(17.5±10.2)% and(15.1±
13.4)%,respectively,at the final concentration of 0.5 mg/mL. There were significant differences in lipid-lowering rate between the
extracts of these 4 compositae plants and simvastatin in vitro(P<0.01). Conclusion:The four plants of C. blinii,A. adenophora,B.
tripartita,and T. diversifolia have significant in vitro lipid-lowering activities,which are worth further study.
