- Abstract: To analyze and identify the chemical constituents from Yinyanghuo Zonghuangtong capsule by using UPLC/Q-TOF-MS/MS. Chromatographic separation was carried out on an Agilent SB-C₁₈ column (2.1 mm×100 mm, 1.8 μm) at the temperature of 30 ℃. The mobile phase was 0.1% formic acid and acetonitrile by gradient elution, with a flow rate at 0.30 mL•min⁻¹, and the injection volume of 2 μL. The MS spectrum was acquired in both negative and positive ion modes using ESI ion source. Based on relative accurate molecular weight, secondary mass spectrometry pyrolysis fragments and chromatographic peak retention time, as well as fragmentation regularity summarized from reference substance and the literature, we could effectively identify the chemical structure of the components under test. As a result, a total of 46 compounds, including flavonoid glycosides, phenolic acids and alkaloids, were successfully identified or tentatively predicted. The results provide technical support for quality control and late-stage clinical application of Yinyanghuo Zonghuangtong capsule, and reference for further expound the pharmacodynamic material basis.
