1、口服当归补血汤后阿魏酸在大鼠体内的组织分布作者：王永禄,王丽瑶，陈国广，张东旭，韦萍【摘要】 目的研究大鼠灌胃给予当归补血汤后阿魏酸在体内的组织分布特性。方法采用高效液相色谱法；色谱柱为KromasilC18（4.6mm×150mm,5μm）；流动相为0.2%甲醇乙腈-0.2%磷酸0.2%三乙胺水溶液（18：82）；检测波长322nm；柱温40℃；流速0.8ml/min。结果各组织中的阿魏酸在10～400ng范围内与峰面积呈良好的线性关系；回收率平均为87.97%±1.95%；日内和日间的RSD分别1.92%～3.87%和3.21%～6.39%之间。阿魏
2、酸在各组织器官中浓度差异较大。结论大鼠灌胃给予当归补血汤后阿魏酸主要在肝脏和肾脏分布，阿魏酸不能通过血脑屏障。【关键词】当归补血汤；阿魏酸；反相-高效液相色谱；组织分布；大鼠 Abstract:ObjectiveToinvestigatethetissuedistributionofferulicacidinratsafteroraladministrationofTangkuEiblood-supplementingdecoction.MethodsHPLCn:KromasilC18（150mm×4.6mm，5μm）;mobilephase:0.2%m
