基于UPLC-MS/MS的临床验方愈疮散化学成分分析OA

OBJECTIVE:To establish an ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)system for the comprehensive analysis of the chemical components of clinical empirical formula Yuchuang powder,to elucidate the fragmentation patterns of representative compounds,and to enhance the quality standards of traditional Chinese medicine preparations.METHODS:UPLC-MS/MS was employed to identify the chemical constituents in Yuchuang powder.The chromatographic separation was performed on an ACQUITY UPLC HSS T3 column(100 mm×2.1 mm,1.8 μm)with gradient elution using a mobile phase consisting of 0.1%formic acid in water and acetonitrile.The injection volume was 10 μL.Automated screening of chemical components was conducted bu using UNIFI software based on the UNIFI traditional Chinese medicine database.The identified compounds were classified and verified by comparison with public databases and published literature,accompanied by fragment ion matching.RESULTS:A total of 80 chemical components were identified,of which 58 were detected in positive ion mode,41 in negative ion mode,and 19 components were detected in both ion modes.Divided by compound categories,it mainly includes 39 terpenes,7 phenanthrene compounds,8 phenolic acids,4 alkaloids,as well as flavonoids,vitamin D derivatives,fatty acids,and other components.CONCLUSIONS:The UPLC-MS/MS method established in the study can identify the pharmacologically active chemical components and characteristic constituents of each medicinal material in Yuchuang powder,providing reference for the rapid identification and quality control of the chemical components of the preparation.
