Keyword:  糖脂益片盐酸小檗碱高效液相色谱法;
Abstract: 目的:建立测定糖脂益片(黄芪、生地、黄连等)中盐酸小檗碱含量的高效液相色谱法.方法:以Symmetry C18(4.6mm×150mm,5μm)为色谱柱,流动相∶乙腈-0.1%磷酸溶液(40∶60)(每100ml加十二烷基磺酸钠0.1g);检测波长:265nm;流速:1.0ml·min-1.结果:盐酸小檗碱线性范围为6.24μg·ml-1~31.2μg·ml-1,r=0.9992(n=5);平均回收率为98.89%,RSD为0.97%(n=9).结论:用该法测定糖脂益片中盐酸小檗碱的含量,操作简单、重复性好、精密度高.
