Objective A ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS) was developed to analyze the chemical compositions of Tongluo Mingmu Capsule (TLMMC). Methods Gradient elution was performed using an Acquity Uplc HSS T3 column (100 mm × 2.1 mm, 1.8 μm) with the mobile phase A of 0.1% formic acid in water and the mobile phase B of 0.1% formic acid in acetonitrile. The flow rate and the injection volume were set to be 0.30 mL/min and 5 μL, respectively. Through the integration of ChemSpider (http://www.ChemSpider.com/), traditional Chinese medicine comprehensive database (TCMID), traditional Chinese medicine systems pharmacology database (TCMSP), Chemical Book (http://www.chemicalbook.com/) and relevant literatures created an internal database for TLMMC. Those chemical components were identified using the internal database previously indicated, mass spectrometry fragment ion information and the relative molecular weight of the reference material. To identify the components the internal database described above, mass spectrometry fragment ion information, and the relative molecular weight of the reference material were used. Results A total of 82 chemical components were qualitatively identified from TLMMC, in which 42 components were determined by comparing the retention time, precise molecular weight and fragment ions of existing reference standards. Other 40 components were predicted according to comparison of the exact molecular weight and fragment ions. The 82 components include 36 flavonoids, eleven triterpenoids, eleven monoterpenoids, eight anthraquinones, and 16 other components. Among them 13 chemical components were from Huangqi (Astragalia Radix), 13 chemical components were from Yinxingye (Ginkgo Folium), eight chemical components were from Chishao (Paeoniae Radix Rubra), eight chemical components were from Mohanlian (Ecliptae Herba), six chemical components were from Dihuang (Rehmanniae Radix), six chemical components were from Fenge (Puerariae Thomosonii Radix), five chemical components were from Dahuang (Rhei Radix et Rhizoma), five chemical components were from Sanqi (Notoginseng Radix et Rhizoma), five chemical components were from Puhuang (Typhae Pollen), five chemical components were from Juemingzi (Cassiae Semen), four chemical components were from Nüzhenzi (Ligustri Lucidi Fructus) and other four chemical components were from Pheretima (Dilong). Conclusion The present UHPLC-Q-TOF-MS method can quickly and comprehensively analyze the chemical profiles of TLMMC, systematically elucidate its pharmacological substance basis and provide a solid theoretical foundation for the elucidation of its mechanism of action and clinical application.
