摘　　要：建立了同时测定加味左金丸中9种药效成分含量的超高效液相色谱-串联质谱(UPLC-MS/MS)分析方法。采用Zorbax RRHD Eclipse Plus C18色谱柱,以含0.2%甲酸的水-甲醇为流动相进行梯度洗脱,流速0.4 mL/min,在电喷雾电离(ESI)正离子模式下,采用多重反应监测模式进行检测。结果表明,芍药苷、延胡索乙素、药根碱、小檗碱、巴马汀、吴茱萸碱、柴胡皂苷C、柴胡皂苷A、柴胡皂苷D的线性范围分别为0.025～5.0 mg/L、0.001 0～2.0 mg/L、0.002 3～7.2 mg/L、0.002 7～28.9 mg/L、0.002 3～9.1 mg/L、0.005 0～1.0 mg/L、0.050～10 mg/L、0.005～1.0mg/L、0.007 5～1.5 mg/L;检出限分别为5.0、0.20、0.45、0.54、0.45、1.0、10、1.0、1.5μg/L。9种成分的加样回收率为99.3%～105%,相对标准偏差均不大于2.6%。该法快捷、准确、重复性好,已成功用于实际样品的分析。A method for the simultaneous determination of paeoniflorin,tetrahydropalmatine,jatrorrhizine,berberine,palmatine,evodiamine,saikosaponin C,saikosaponin A and saikosaponin D in Jiaweizuojin Pills was established by ultra performance liquid chromatography with tandem mass spectrometry（UPLC-MS/MS）.The UPLC separation was performed on a Zorbax RRHD Eclipse Plus C_18 column（50 mm×2.1 mm,1.8μm） by using 0.2%（v/v） formic acid aqueous solution and methanol as mobile phases with the gradient elution at a flow rate of 0.4 mL/min.The analytes were detected by tandem mass spectrometry under the positive ion mode with the electrospray ionization（ESI） source and in the multiple reaction monitoring（MRM） mode.Under the optimized conditions,the calibration curves were linear in the ranges of 0.025-5.0 mg/L for paeoniflorin,0.0010-2.0 mg/L for tetrahydropalmatine,0.0023-7.2 mg/L for jatrorrhizine,0.0027-28.9 mg/L for berberine,0.002 3-9.1 mg/L for palmatine,0.0050-1.0 mg/L for evodiamine,0.050-10 mg/L for saikosaponin C,0.0050-1.0 mg/L for saikosaponin A and 0.0075-1.5 mg/L for saikosaponin D with the detection limits of 5.0,0.20,0.45,0.54,0.45,1.0,10,1.0,1.5 μg/L,respectively.The average recoveries of the nine effective components were between 99.3% and 105% with the relative standard deviations not more than 2.6%.The developed method is simple,rapid and accurate,and suitable for the quality control of the nine effective components in Jiaweizuojin Pills.
