Objective: To establish an ultra-high performance liquid chromatography tandem mass spectrometry(UPLC-MS/MS)method for the simultaneous determination of 22 components of Bimin capsules, including benzoylaconine, benzoylmesaconine, benzoylhypacoitine, hypaconitine, mesaconitine, fuziline, aconitine, aconine,mesaconine, isoliquiritigenin, echinatin, protocatechuic acid, liquiritigenin, isoliquiritoside, glycycoumarin,naringenin, schaftoside, licochalcone B, glycyrrhizic acid ammonium salt, liquiritin, liquiritin apioside and isoliquiritin apioside. Methods: The AcclaimTM RSLC 120C18 column (2.1 mm×100 mm, 2.2 μm) was used with 0.05% formic acid water (A) and acetonitrile (B) as the mobile phase at a flow rate of 0.4 mL · min-1. Electrospray ionization (ESI) source and multiple reaction monitoring (MRM) mode in both positive and negative were used for ion detections. Resulets:The 22 components displayed a good linear relationship (R2>0.990) in their respective ranges, and the precision, repeatability, stability, and sample recovery rate all met the requirements. It was found that all 22 components were detected in the nasal sensitivity capsules, with significant differences in the content of some components. Conclusion: This method is fast, simple, sensitive and reliable, and can provide scientific basis for the quality control of the Bimin capsules.
