摘要
用高效液相色谱法测定金薏尿石颗粒剂及大黄药材中大黄酸、大黄素、大黄酚、大黄素甲醚和芦荟大黄素的含量.选用AltimaC18分析柱(250mm×4.6mm,5μm),流动相:甲醇—0.1%磷酸溶液(9010),检测波长:440nm,流速:1.0mL/min,柱温:30℃.颗粒剂中各成分的平均回收率分别为大黄酸98.1%(RSD=1.9%)、大黄素97.8%(RSD=2.9%)、大黄酚97.9%(RSD=2.4%)、大黄素甲醚97.0%(RSD=1.0%)和芦荟大黄素100.9%(RSD=2.3%).方法快速、灵敏、准确,样品处理简便易行.
HPLC was used to determine the contents of rhein,emodin,chrysophanol,physcion and aloe-emodin in JinYiNiaoShi granules and rhubarb radix.The HPLC system consisted of Alltima C18 column(250mm×46mm,5μm),methanol—01% phosphoric acid(90∶10)mixture as mobile phase,with detection at 440nm,flow rate 10mL/min and column temperature at 30℃.For JinYiNiaoShi granules,the mean recovery of 981%(RSD=19%)for rhein,978%(RSD=29%)for emodin,979%(RSD=24%)for chrysophanol,970%(RSD=10)for physcion and 1009%(RSD=23%)for aloe-emodin is obtained,respectively.The method is sensitive,rapid and accurate.
