Objective: To establish an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS)method for the simultaneous determination of 15 components(neochlorogenic acid, protocatechuic acid,4-hydroxybenzoic acid, chlorogenic acid,cryptochlorogenin acid,sweroside,schaftoside,agnuside, isoschaftoside, vitexin-2-O-rhamnoside, vitexin, luteolin, isochlorogenic acid B, isochlorogenic acid A and isochlorogenic acid C)in Jinmu Ganmao tablets.Methods: The separation was performed on a CORTECS UPLC C18 column(100 mm×2. 1 mm, 1. 6 μm). Acetonitrile and water(containing 0. 1% formic acid)were adopted as the mobile phase by gradient elution at a flow rate of 0. 25 mL·min-1. MS detection was performed with multiple reaction monitoring mode.Results: The developed method showed good linearity(r > 0. 994 0)for all the analytes within the test ranges. The overall average recovery rates were in the range of 96. 8%-104. 5% with RSD of 3. 8%-4. 6%. The contents of neochlorogenic acid, protocatechuic acid, 4-hydroxybenzoic acid, chlorogenic acid,cryptochlorogenin acid,sweroside, schaftoside, agnuside, isoschaftoside, vitexin-2-O-rhamnoside, vitexin, luteolin, isochlorogenic acid A, B and C in twelve samples were 0. 300-0. 630 mg·g-1, 0. 013-0. 031 mg·g-1, 0. 053-0. 133 mg·g-1, 2. 319-4. 290 mg·g-1, 0. 442-0. 792 mg·g-1, 0. 345-0. 715 mg·g-1, 0. 476-0. 945 mg·g-1, 0. 164-0. 283 mg·g-1, 0. 068-0. 162 mg·g-1, 0. 004-0. 006 mg·g-1, 0. 006-0. 013 mg·g-1, 0. 064-0. 100 mg·g-1,0. 974-1. 682 mg·g-1,0. 423-0. 690 mg·g-1 and 0. 799-1. 636 mg·g-1,respectively.Conclusion: The UPLC-MS/MS method could be used for the quality control of Jinmu Ganmao tablets.
