Analysis of Chemical Constituents in Male Flowers of Eucommia ulmoides by Liquid Chromatography Coupled with Electrospray Ionization-Triple Quadrupole-Time of Flight-Tandem Mass Spectrometry (LC-ESI-Triple TOF-MS/MS)
摘要
Abstract
The chemical constituents in male flowers of Eucommia ulmoides were analyzed by liquid chromatography coupled with electrospray ionization-triple quadrupole-time of flight-tandem mass spectrometry (LC-ESI-Triple TOF-MS/MS).The separation and analysis were carried out on a reversed-phase C18 column with gradient elution using 0.1％ formic acid (A)-acetonitrile (B) under the negative ionization mode of ESI.According to the accurate mass of quasimolecular and product ions provided by Triple TOF-MS/MS,a total of 32 constituents were identified or tentatively presumed by comparing with reference standards and literature data,including 2 lignans,9 iridoids,8 penylpropanoids,12 flavonoids and one phenolic glycoside.This study may provide basic information for further research on the pharmacodynamic material basis and intensive utilization of male flowers of Eucommia ulmoides.关键词
