AbstractThe Ultra-high Performance Liquid Chromatography Quadrupole Time-of-flight Mass Spectrometry（UPLC-Q-TOF-MS）was applied to analyze the chemical components in Lysinotus wilsonii. A Waters ACQUITY UPLC-BEH-C₁₈ S column（2.1 mm×100 mm,1.7 μm）was used with a gradient elution of acetonitrile-water containing 0.1％ formic acid. The mass spectrometry equipped with ionization source was used and the data was collected in negative ion mode. Results showed that 57 components were identified as 42 phenylethanoid glycosides, 5 benzyl alcohol glycosides, 6 flavonoids and 4 other components. Among them, 43 compounds were firstly identified in Gensneriaceae and one benzyl alcohol glycoside may be a new compound. We have quite completely identified the components in L. wilsonii for the first time, which may lay the foundation for further study and utilization of the medicinal plant.Copyright© by the Chinese Pharmaceutical Association.
