Objective To establish an UHPLC-MS/MS method for rapid and simultaneous determination of the content of 13 components in Ainsliaea fragrans. Methods The UHPLC-MS/MS method was performed on UPLC BEH C₁₈ (100 mm×2.1 mm, 1.7 μm) with acetonitrile-water (containing 0.1% formic acid and 5 mmol ammonium formate) as mobile phase for gradient elution. Flow rate was 0.25 mL/min and column temperature was 40℃. A triple quadrupole mass spectrometer equipped with electrospray ionization source (ESI) was applied in negative ion mode with the following parameters:ion spray, −4 500 V, ion source temperature, 500℃, curtain gas, 344.5 kPa, nubulizer (GS1), 344.5 kPa, heater gas (GS2), 206.7 kPa, and multiple reaction monitoring (MRM) was performed for quantitative analysis of these compounds. Results Under the optimized MS/MS condition, the linearity ranges of protocatechuic acid, caffeic acid, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, 1,3-dicaffeoylquinic acid, 1,5-dicaffeoylquinic acid, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid, luteolin, luteoloside and apigenin were 1.099-274.800 ng/mL, 1.006-100.600 ng/mL, 1.080-1 080.000 ng/mL, 83.12-8 312.00 ng/mL, 19.92-996.00 ng/mL, 1.076-269.000 ng/mL, 5.555-555.500 ng/mL, 4.420-4 420.000 ng/mL, 44.76-17 904.00 ng/mL, 48.00-9 600.00 ng/mL, 2.108-210.800 ng/mL, 4.136-413.600 ng/mL, 1.070-107.000 ng/mL (r ≥ 0.9958), respectively, with good linearity. The average recovery rate of thirteen compounds in the samples were in the range of 96.54%-99.75%, and the RSD range was from 0.48% to 0.96%. The RSD values of precision, stability and repeatability test were all less than 3.90%. Conclusion The method had good repeatability, high specificity, stability and controllability, and could be used for quality control of A. fragrans and its preparations.
