OBJECTIVE
To make a qualitative analysis on chemical components in Ligustrum lucidum by UPLC-ESI-Q-TOF-MS.
METHODS
ACQUITY UPLC BEH C18 (2.1 mm x 100 mm, 1.7 microm) column was adopted, with methyl cyanides-0.1% formic acid as the mobile phase for gradient elution; ESI ion source was used for mass spectra, and data were collected in positive and negative mode.
RESULTS
Fourteen compounds of L. lucidum were identified by analyzing positive and negative ion mass spectra information and element composition and comparing controls with data from relevant literature.
CONCLUSIONS
After the separation by ultra high performance liquid chromatography, relative molecular mass was determined by mass spectra, and chemical compounds in L. lucidum were determined by information search through relevant literature data, in order to provide powerful therapeutic material basis for L. lucidum.
