摘要： 应用胶束电动毛细管色谱-电喷雾电离质谱联用法同时测定了妇宁栓中的小檗碱、巴马汀、苦参碱、儿茶素和黄芩苷5种主要有效成分的含量。在未涂层石英毛细管柱(80 cm×50 μm)中,以40 mmol/L月桂酸-100 mmol/L氨水溶液(含25%的乙腈,pH 9.5)为缓冲液,分离电压为25.0 kV,各组分在16 min内得到完全分离。电喷雾质谱检测时采用50%异丙醇水溶液(含3 mmol/L乙酸)为鞘液。结果表明,小檗碱、巴马汀、苦参碱、儿茶素、黄芩苷的线性范围分别为0.03～15、0.05～15、0.2～250、1.5～300和2.0～500 mg/L,检出限分别为0.01、0.02、0.05、0.5、0.6 mg/L。5种组分的加标回收率为94.0%～104.0%,相对标准偏差(RSD)在0.3%～3.2%之间。该法简便、快速、准确,重现性好,可用于妇宁栓中小檗碱、巴马汀、苦参碱、儿茶素、黄芩苷含量的同时测定。

Abstract: A method for the simultaneous determination of berberine, palmatine, matrine, catechin and baicalin in Funing Shuan was established using micellar electrokinetic capillary chromatography-electrospray ionization mass spectrometry (MEKC-ESI MS). The compounds were separated on an uncoated capillary (80 cm×50 μm) with the operating voltage of 25 kV and the running buffer of 40 mmol/L lauric acid-100 mmol/L ammonia mixture containing 25% acetonitrile (pH 9.5). The baseline separation of the five compounds was achieved within 16 min with a satisfactory repeatability and sensitivity. The solution of 50% 2-propanol/water solution (containing 3 mmol/L acetic acid) was used as the sheath liquid for the ESI MS analysis. The results showed that the linear ranges for berberine, palmatine, matrine, catechin and baicalin were 0.03~15, 0.05~15, 0.2~250, 1.5~300 and 2.0~500 mg/L, respectively, and the detection limits were 0.01, 0.02, 0.05, 0.5 and 0.6 mg/L, respectively. The average recoveries of the five components were between 94.0%~104.0% with the relative standard deviations (RSDs) of 0.3%~3.2%. The developed method is simple, rapid, and accurate, and it is suitable for the routine analysis of the five effective components in Funing Shuan.
