Abstract:
Xiaoer-Feire-Kechuan (XFK) is an 11-herb Chinese medicine formula to treat cough and pulmonary inflammation.The complicated composition rendered its chemical analysis and effective-component elucidation.In this study,we combined quantitative analysis and bioactivity test to reveal the anti-inflammatory constituents of XFK.First,UPLC-DAD and UHPLC/Q-Orbitrap-MS methods were estab-lished and validated to quantify 35 analytes (covering 9 out of 11 herbs) in different XFK formulations.Parallel reaction monitoring mode built in Q-Orbitrap-MS was used to improve the sensitivity and selectivity.Then,anti-inflammatory activities of the 35 analytes were analyzed using in vitro COX-2 inhibition assay.Finally,major analytes forsythosides H,I,A (8-10),and baicalin (15) (total contents varied from 21.79 to 91.20 mg/dose in different formulations) with significant activities (inhibitory rate ≥ 80%) were proposed as the anti-inflammatory constituents of XFK.The present study provided an effective strategy to discover effective constituents of multi-herb formulas.
