Abstract:
Objective: To study the chemical constituents of Changyanning Tablets, a high performance liquid chromatography-quadrupole time of flight mass spectrometry (HPLC-Q-TOF-MS/MS) was established to recognize and classify the ingredients accurately and rapidly. Methods: Agilent ZORBAX Eclipse XDB-C18 chromatographic column (250 mm × 4.6 mm, 5 μm) was employed and the separation was performed with the mobile phase consisting of methanol-0.05% acetic acid aqueous solution. The information of accurate mass and multistage fragment ions were obtained by the monitored simultaneously for positive and negative ions. The main chemical constituents of Changyanning Tablets were identified by high resolution mass spectrometry data, combining with Pubmed, Hmdb, Massbank network database, reference literature and comparing the reference. Results: Fifty-one chemical components were finally identified in this study, including two phenylpropanoids, eight iridoids, 12 flavonoids, four tannins, 23 organic acids, and two other classes. Conclusion: This study comprehensively studies the material basis in Changyanning Tablets, which provides a basis for improving the quality evaluation system of Changyanning Tablets and lays the foundation for elucidating the active components mechanism.
