An Analysis of Chemical Components of Tongluo Yiqing Prescription Based on Ultra-performance Liquid Chromatography-Orbitrap-Mass Spectrometry/Mass Spectrometry
Objective To perform rapid analysis and preliminary identification of the chemical components of Tongluo Yiqing Prescription by ultra-performance liquid chromatography-orbitrap-mass spectrometry/mass spectrometry (UPLC-Orbitrap-MS/MS).Methods UPLC was performed on a ZORBAX Eclipse Plus C18 column with acetonitrile-0.1% formic acid for gradient elution at a flow rate of 0.4 mL/min and a column temperature of 35 ℃.Mass spectrometry was performed in the positive and negative electrospray ionization modes, and with reference to related articles, retention time, accurate relative molecular weight,and secondary mass spectrometry fragments were used to perform the analysis and preliminary identification of the chemical components obtained.Results Based on the established chromatographic conditions,a total of 94 chemical components were identified from Tongluo Yiqing Prescription,among which there were 31 flavonoids,14 phenolic acids,9 fatty acid com-pounds,6 saponins,5 isoflavones,4 amino acids,4 triterpenoids,4 aldehydes,3 polypeptides,3 phenylpropanoids,3 alcohols, and 8 compounds of other types.Eight repeated components were obtained in the positive and negative electrospray ionization modes.Conclusion The UPLC-Orbitrap-MS/MS technique can rapidly and preliminarily identify the chemical components in Tongluo Yiqing Prescription,which can provide a basis for the research on the material basis of Tongluo Yiqing Prescription and the research and development of new drugs.
