目的 建立同时测定通塞脉微丸中10种有效成分（绿原酸、芹糖甘草苷、毛蕊异黄酮苷、木犀草苷、甘草苷、阿魏酸、异甘草苷、哈巴俄苷、甘草素和肉桂酸）的超高效液相色谱-串联质谱（UPLC-MS/MS）分析方法。方法 采用BEHC₁₈（100 mm×2.1 mm，1.7 μm）色谱柱，流动相为乙腈-0.1%甲酸水溶液，梯度洗脱，体积流量为0.3 mL/min，采用电喷雾电离源（ESI），多反应离子监测（MRM）扫描方式进行检测。结果 10种成分线性关系分别为绿原酸Y＝294.09 X＋17 624；芹糖甘草苷Y＝19.296 X＋748.42；毛蕊异黄酮苷Y＝670.8 X＋11 121；木犀草苷Y＝490.45 X＋2 938.3；甘草苷Y＝33.489 X＋555；阿魏酸Y＝127.76 X＋1 343.5；异甘草苷Y＝57.87 X＋804.81；哈巴俄苷Y＝13.125 X－20.365；甘草素Y＝29.057 X＋367.71；肉桂酸Y＝72.867 X＋1 301.5，且各相关系数（r）均大于0.999 0。精密度、重复性和稳定性良好；加样回收率在96.00%～104.67%，RSD值均小于3%。结论 所建立的方法准确、快捷，重复性好，可用于通塞脉微丸中绿原酸、芹糖甘草苷、毛蕊异黄酮苷、木犀草苷、甘草苷、阿魏酸、异甘草苷、哈巴俄苷、甘草素和肉桂酸10种有效成分的同时测定。

Objective To establish a UPLC-MS/MS method for simultaneously determining ten components (chromogenic acid, liquiritin apioside, calycosin-7-glucoside, cynaroside, liquiritin, ferulic acid, isoliquiritoside, harpagoside, liquiritigenin, and cinnamic acid) in Tongsaimai Pellets. Methods A method for the simultaneous determination of the ten components was established by UPLC-MS/MS. The analysis was performed on a Waters Acquity BEH C₁₈ column (100 mm × 2.1 mm, 1.7 μm) with the mixture of acetonitrile and 0.1% formic acid/water as mobile phase, and the gradient elution at a flow rate of 0.3 mL/min. The analytes were detected by tandem mass spectrometry with the electrospray ionization (ESI) source combined with multiple reaction monitoring (MRM) mode. Results The linear relationships between the concentration and peak areas of the ten components were chromogenic acid Y = 294.09 X + 17 624; liquiritin apioside Y = 19.296 X + 748.42; calycosin-7-glucoside Y = 670.8 X + 11 121; cynaroside Y = 490.45 X + 2 938.3; liquiritin Y = 33.489 X + 555; ferulic acid Y = 127.76 X + 1 343.5; isoliquiritoside Y = 57.87 X + 804.81; harpagoside Y = 13.125 X－20.365; liquiritigenin Y = 29.057 X + 367.71; cinnamic acid Y = 72.867 X + 1 301.5 (r > 0.999 0); The precisions, repeatabilities, and stabilities of the method were satisfactory, and the average recoveries were between 96.00% and 104.67% with the relative standard deviations no more than 3%. Conclusion The established method is specific, rapid, and accurate for the determination of the ten effective components in Tongsaimai Pellets.
