Objective The chemical constituents of Huoxue Jiedu Decoction were studied by ultra-high performance liquid chromatography-four-stage rod-time-of-flight mass spectrometry (UPLC-Q-TOF/HRMS^E). Method ACQUITY UPLC BEH C₁₈ column (100 mm×2.1 mm, 1.8 μm) was used for gradient elution with 0.1% formic acid aqueous solution (A) and 0.1% acetonitrile formate (B) as mobile phases. The volume flow rate was 0.3 mL/min. ESI source was used to collect data in positive and negative ion modes. According to the precise relative molecular weight and secondary fragment ion information of compounds, the main chemical constituents of Huoxue Jiedu Formula were identified with reference data and UNIFI database. Results Sixty-six chemical constituents were identified from Huoxue Jiedu Recipe, including eight flavonoids, seven alkaloids, six phenolics, 30 saponins, six lignins, four terpenoids and five other compounds. Conclusion The established UPLC-Q-TOF/HRMS^E combined with UNIFI method can identify a variety of chemical components systematically, quickly and accurately, which provides a reference for the selection of quality evaluation indexes and in-depth study of the material basis of its efficacy.
