Abstract
目的 建立同时测定玉叶解毒颗粒中绿原酸和槲皮素两种主要成分含量的HPLC方法.方法 采用Phenomenonex Gemini C18色谱柱(250 mm×4.6 mm,5μm),以甲醇(A)-0.4%磷酸水溶液(B)为流动相,梯度洗脱(0~20 min,80%A→55% A;30~45 min,15%A→0%A),流速1m/min,检测波长为345 nm.结果 玉叶解毒颗粒中绿原酸、槲皮素的含量范围分别为:0.30~3.00 μg/g,0.18~1.8 μg/g,且线性关系良好;平均回收率分别为99.930%、95.005%,RSD均小于2.0%.结论 该检测方法简便,可靠,稳定.经方法学验证,可用于同时检测玉叶解毒颗粒中绿原酸和槲皮素的含量.
