Abstract
目的 建立HPLC法同时测定银黄颗粒(金银花、黄芩提取物)中绿原酸、咖啡酸、木犀草苷、黄芩苷、木犀草素、芦丁的含有量.方法 该药物80%甲醇提取液的分析采用SunFire-C18色谱柱(250mm×4.6 mm,5μm);以乙腈-0.4%磷酸为流动相,梯度洗脱;体积流量1.0 mL/min;柱温30℃;检测波长239 nm.结果 6种成分在各自线性范围均呈良好的线性关系(r=0.999 9),平均加样回收率94.56%~98.38%,RSD 0.49% ~2.89%.14批样品中黄芩苷含有量差异较小,其他5种成分含有量差异较大.结论 不同厂家银黄颗粒和金银花提取物的质量参差不齐,应加强监管.
