Analysis of Chemical Constituents in the Leaves of Pluchea Indica(L.) Less. by UPLC-Q-TOF-MS/MS
The main chemical constituents in the leaves of, Pluchea indica,(L.) Less,. ,were qualitatively analyzed with ultra-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS/MS). The analytes were separated on a Waters UPLC BEH C,18,(2.1 mm×100 mm,1.7 μm) by gradient elution,with acetonitrile-0.1% formic acid solution as the mobile phase,and then analyzed in both positive and negative ion modes. A total of 52 chemical constituents were identified by mass spectrometry database,fragmentation regularities of mass spectra,consulting literature reports,retention time and mass data of reference compounds,including 2 coumarins,15 flavonoids,16 phenylpropanoids,5 alkaloids,5 fatty acids,3 organic acids,3 amino acids,1 phenolic acid,and 2 other compounds,of which 23 compounds were firstly reported for the leaves of ,Pluchea indica,(L.) Less.,and 11 compounds were verified by reference substance. The method is accurate,reliable and efficient,which is suitable for rapid identification of ingredients in the leaves of ,Pluchea indica,(L.) Less.,and can provide a basis for the pharmacodynamic mechanism and clinical application of the leaves of ,Pluchea indica,(L.) Less..
