目的初步筛选茵陈蒿汤保肝退黄药效部位。方法茵陈蒿汤煎煮提取,水煎液(A)分次加入乙醇,使含醇量分别达到20%和60%,取20%乙醇沉淀部位(B)、60%乙醇沉淀部位(C),最终的上清液回收乙醇(D),α-萘异硫氰酸酯(ANIT)诱导大鼠胆汁淤积型黄疸模型,观察A、B、C、D对模型大鼠血清中丙氨酸氨基转移酶(ALT)、碱性磷酸酶(ALP)、总胆红素(TBIL)及总胆汁酸(TBA)的影响,光学显微镜下观察大鼠肝组织病理变化,并根据病理分析赋值标准进行半定量分析。结果与模型对照组比较,D部位组大鼠血清指标均显著下降(P<0.05),肝组织病变明显改善,病理改变赋值显著下降(P<0.01),其余各部位组血清学指标及肝组织病理改变赋值均下降不明显(P>0.05)。结论茵陈蒿汤具有一定的保肝退黄作用,其药效物质主要存在于其水煎液的60%乙醇沉淀的上清液部分。
