摘要:
目的:建立四季三黄片中同时测定芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚含量的方法。方法:色谱柱为Agela Venusil XBP-C18柱(4.6 mm×250 mm,5μm),流动相乙腈-0.1%磷酸,梯度洗脱,流速1.0 mL.min-1,检测波长226nm。结果:芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚分别在0.040~0.800,0.040~0.800,0.040~0.800,0.040~0.800,0.020~0.400μg呈良好的线性关系,平均回收率(n=6)分别为97.62%,99.48%,99.72%,96.23%,95.68%,RSD1.62%,1.24%,1.13%,1.19%,1.67%。结论:所建立的定量方法快速简单,方法可靠,可作为四季三黄片的质量控制方法。
