Abstract:
Objective: To analyze and identify the chemical constituents from Lindley eupatorium by using UPLC-Q-TOF/MS. Methods: The separation was performed on Waters Acquity UPLC BEH C18 (100 mm × 2.1 mm, 1.7 μm) column with gradient elution of 0.1% formic acid (A)-acetonitrile (B), the flow rate was 0.2 mL/min. The column temperature was set at 35 ℃. The MS analysis was based on information associated mode (IDA), and positive and negative ions were collected respectively. Results: A total of 26 compounds in L. eupatorium were identified by PeakView, combined with the mass spectrometry data of each chromatographic peak in the database, and the cleavage law of secondary fragment of each peak of which11 compounds were first reported for L. eupatorium. The main chemical constituents included flavonoids, nucleosides, alkaloids, phenylpropanoid, sesquiterpenoids, coumarins, polyols, etc. Conclusion: The method is accurate, reliable and effficient, which is suitable for rapid identification of ingredients in L. eupatorium, which provides a reference for clarify its efficacy and material basis.
