Abstract
目的:建立反相-高效液相色谱法同时测定消炎颗粒中绿原酸、秦皮乙素的含量,为更好地控制药品质量提供参考。方法:采用Inertsil ODS-3色谱柱(4.6 mm ×250 mm,5μm);流动相为乙腈-0.1%磷酸溶液(V∶V=10∶90),流速为1.0 ml/min,柱温为30℃,检测波长分别为327 nm(绿原酸)、353 nm(秦皮乙素)。结果:指标成分绿原酸、秦皮乙素进样量各在0.103~0.821、0.107~0.854μg范围内呈良好的线性关系(r≥0.9998),加样回收率分别为99.57%(RSD=1.06%)、101.06%(RSD=1.27%)。结论:本法简便可靠、重复性好,适用于该制剂的质量控制。
