目的 建立UPLC-MS/MS法同时测定透骨香中原儿茶酸、表儿茶素、绿原酸、槲皮苷、白珠树苷、滇白珠苷A的含量.方法 分析采用Waters BEH C18色谱柱(2.1 mm×100 mm,1.7 μm);流动相水(含 0.1%甲酸)-乙腈(含0.1%甲酸),梯度洗脱;体积流量 0.3 mL/min;柱温 40℃;电喷雾离子源;正负离子扫描;多反应监测模式.采用层次聚类分析(HCA)、主成分分析(PCA)筛选影响药材质量的重要成分.结果 6 种成分在各自范围内线性关系良好(r≥0.998 2),平均加样回收率 98.76%~101.88%,RSD 1.0%~2.5%.透骨香根、地上部分所含成分有较大差异,白珠树苷、表儿茶素、原儿茶酸是质量标志成分.结论 该方法准确、高效,可用于透骨香的质量控制.
Simultaneous content determination of six constituents in Gaultheria leucocarpa var.yunnanensis by UPLC-MS/MS
AIM To establish an UPLC-MS/MS method for simultaneous content determination of protocatechuic acid,epicatechin,chlorogenic acid,quercitrin,gaultherin and gaultheroside A in Gaultheria leucocarpa var.yunnanensis.METHODS The analysis was performed on a 40℃thermostatic Waters BEH C18 column(100 mm×2.1 mm,1.7 μm),with the mobile phase comprising of water(containing 0.1%formic acid)-acetonitrile(containing 0.1%formic acid)flowing at 0.3 mL/min in a gradient elution manner,and electron spray inoization source was adopted in positive and negative ion scanning with multiple reaction monitoring(MRM)mode.Hierarchical cluster analysis(HCA)and principal component analysis(PCA)was used to screen important components that affect the quality of medicinal materials.RESULTS Six constituents showed good linear relationships within their own ranges(R2≥0.998 2),whose average recoveries were 98.76%-101.88%with the RSDs of 1.0%-2.5%.The constituents of G.leucocarpa in the roots and aerial parts were quite different.Gaultherin,epicatechin and protocatechuic acid may be the quality mark constituents of G.leucocarpa.CONCLUSION This accurate and efficient method can be used for the quality control of G.leucocarpa.
