Abstract
目的 建立补肾强身片(淫羊藿、菟丝子、金樱子等)UPLC指纹图谱.方法 该药物50%乙醇提取液的分析采用Agilent SB-C18色谱柱(100 mm ×4.6 mm,2.7 μm);以乙腈-0.1%磷酸为流动相,梯度洗脱;体积流量0.5 mL/min;检测波长215 nm;柱温40℃.再通过聚类分析、主成分分析、正交偏最小二乘判别分析对指纹图谱进行评价.结果 12批样品的UPLC指纹图谱中有20个共有峰,并鉴定出9个(原儿茶酸、红景天苷、绿原酸、金丝桃苷、特女贞苷、朝藿定C、淫羊藿苷、山柰素、宝霍苷Ⅰ),相似度0.843~0.970.12批样品可分成3类,并找到4个差异标志物,包括特女贞苷和绿原酸.结论 该方法简便可靠,可用于补肾强身片的质量控制.
