| Objective To identify the chemical constituents of Yixinshu capsules by ultra-high performance liquid chromatographyquadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS).Methods From September to December 2021, the 50 % methanol ex tract of Yixinshu capsules was analyzed on Waters ACQUITY UPLC HSS T3 column (2.1 mm×100 mm, 1.8 μm) and eluted with 0.1%formic acid and acetonitrile in gradient elution.The flow rate was set at 0.3 mL/min and the column temperature was maintained at 30 °C. By applying software MassLynx V4.1, the chemical constituents of Yixinshu capsules were identified according to the retention times, quasi-molecular ions, and MS/MS ions, and referring to the reference standards and literatures.Results In total, 86 compounds were identified in Yixinshu capsules, including 35 saponins, 16 phenolic acids, 20 diterpenes, 9 lignans and 6 other compounds.Con clusion The method is accurate and stable, and quickly elucidates the chemical compositions of Yixinshu capsules. The clarification of the material basis of Yixinshu capsules provids strong support for its quality control, determination of active ingredients, and research on its therapeutic mechanism. |
