ABSTRACT
A UHPLC-Q Exactive Orbitrap MS method was used to analyze the chemical constituents of the classical prescription Qianghuo Shengshi Standard Decoction(QHSS). UHPL conditions were as follows: Waters~(TM) UPLC~(TM) HSS T3 C_(18) column(2.1 mm×100 mm, 1.7 μm) and mobile phase of acetonitrile-0.1% formic acid aqueous solution. Mass spectrometry data of QHSS, each herb extract, and negative sample were collected in both positive and negative ion modes. The chemical constituents of QHSS were identified or tentatively identified based on the accurate molecular weight, retention time, MS fragmentation, comparison with reference substances, and literature reports. A total of 141 compounds were identified, including 18 amino acids, oligosaccharides, oligopeptides, and their derivatives, 19 phenolic acids, 44 coumarins, 18 flavonoids and chromones, 13 saponins, 17 phthalides, and 12 other components. This study comprehensively characterized the chemical constituents of QHSS, laying an experimental basis for the in-depth research on the material basis and quality control of QHSS.
