Abstract
目的 建立同时测定大血藤中原儿茶酸、红景天苷和绿原酸含量的HPLC法.方法 色谱柱为Waters XSELECT CSH C18(150 mm×4.6 mm,5μm),以乙腈-甲醇-0.2%磷酸水为流动相进行梯度洗脱,体积流量0.8 ml/min,检测波长260 nm,柱温35℃.结果 原儿茶酸、红景天苷和绿原酸分别在0.0020~0.0120、0.0600~0.3602和0.0750~4.5006 mg/ml内呈良好线性关系,平均加样回收率分别为98.01%、98.53%、101.10%,RSD分别为0.07%、0.12%、0.92%.结论 该方法操作简便、准确、重复性好,可为大血藤质量控制提供依据.
