摘 要:目的:建立运用液相色谱-串联质谱法同时测定一清胶囊中9个成分(黄芩苷、汉黄芩苷、黄连碱、药根碱、巴马汀、小檗碱、大黄素、大黄酚、大黄素甲醚)含量的分析方法。方法:采用Agilent SB-C18色谱柱(2.1 mm×50 mm,1.8μm),以水-甲醇为流动相,梯度洗脱(0~4.5 min,20%B→70%B;4.5~8 min,70%B→95%B;8~8.5 min,95%B→20%B),流速0.3 mL.min-1,柱温为室温;采用电喷雾离子源(ESI),动态多反应监测扫描模式(DynamicMRM)进行定量分析,干燥气温度350℃,干燥气流量10 L.min-1,雾化器压力275.8 kPa,毛细管电压4 kV。结果:黄芩苷、汉黄芩苷、黄连碱、药根碱、巴马汀、小檗碱、大黄素、大黄酚、大黄素甲醚的质量浓度分别在2.712~27.12μg·mL-1(r=0.9989)、0.8800~8.800μg·mL-1(r=0.9991)、0.5280~5.280μg·mL-1(r=0.9982)、0.1272~1.272μg·mL-1(r=0.9977)、0.3024~3.024μg·mL-1(r=0.9979)、1.196~11.96μg·mL-1(r=0.9995)、33.28~332.8 ng.mL-1(r=0.9988)、32.40~324.0 ng.mL-1(r=0.9974)、8.800~88.00 ng.mL-1(r=0.9977);平均加样回收率(n=6)均在97.5%~101.9%范围内,RSD均小于2.4%。结论:该分析方法特异、快速、灵敏,重复性好,可为一清胶囊的质量控制提供依据。Objective: To establish an LC-MS /MS method for simultaneous content determination of the nine components(baicalin,wogonoside,coptisine,jatrorrhizine,palmatine,berberine,emodin,chrysophanol,physcion) in Yiqing capsules.Methods: The HPLC analysis was performed on an Agilent SB-C18 column(2.1 mm × 50 mm,1.8 μm) with gradient elution using water and methanol as the mobile phase(0-4.5 min,20% B→70%B;4.5-8 min,70% B→95% B;8-8.5 min,95% B→20% B).The flow rate was 0.3 mL.min-1,the column temperature was room temperature.Electrospray ionization(ESI) source was used.Quantization was performed using selected dynamic multiple reaction monitoring(DynamicMRM) mode(gas tempereture: 350 ℃;gas flow: 10 L.min-1;nebulizer: 275.8 kPa;capillary: 4 kV).Results: The method has a good linearity in the ranges of 2.712-27.12 μg.mL-1(r = 0.9989) for baicalin,0.8800-8.800 μg.mL-1(r = 0.9991) for wogonoside,0.528-5.280 μg.mL-1(r =0.9982) for coptisine,0.1272-1.270 μg.mL-1(r =0.9977) for jatrorrhizine,0.3024-3.024 μg.mL-1(r = 0.9979) for palmatine,1.196-11.96 μg.mL-1(r = 0.9995) for berberine,33.28-332.8 ng.mL-1(r = 0.9988) for emodin,32.40-324.0 ng.mL-1(r = 0.9974) for chrysophanol,8.800-88.00 ng.mL-1(r = 0.9977) for physcion.The average recoveries of nine active components were 97.5%-101.9% with RSDs(n = 6) of less than 2.4%.Conclusion: The method is specific,rapid,sensitive and reliable.It may provide a basis for the quality control of Yiqing capsules.
