目的:建立地肤子的高效液相色谱(HPLC)指纹图谱。方法:选择安捷伦TC-C_(18)色谱柱,二极管阵列检测器(DAD),流动相为乙腈-0.1%磷酸水溶液,梯度洗脱,总流速1 m L/min,检测波长355 nm,柱温25℃,进样量为10μL。采用《中药色谱指纹图谱相似度评价系统A版》对10批次的地肤子进行相似度分析,选择共有峰的相对峰面积对样品进行聚类分析。结果:HPLC指纹图谱共发现19个共有峰,其中14号峰为芦丁。10批次地肤子与对照图谱相似度均>0.95。聚类分析结果显示,地肤子药材可归为3类,相同产地药材可归为1类,说明不同产地药材中成分的含量有明显区别。结论:该方法稳定性、重复性良好,可用于地肤子药材的质量评价和鉴定。
