METHOD： Based on the chromatographic retention behavior, fragmentation patterns of chemical components, and published lit- eratures, a high-performance liquid chromatography coupled with electrospray ionization quadrnpole time-of-flight tandem mass spectrometry （HPLC-ESI-Q-TOF/MS） method was established to characterize and identify components in Jinqi Jiangtang tablets. RESULTS： A total of 52 chemical compounds, including eight iridoid glycosides, seven phenolic acids, twelve alkaloids, six fla- vonoids, and nineteen saponins, were identified in Jinqi Jiangtang tablets. CONCLUSION： The established method could serve as a powerful tool for structural characterization and quality control of this Chinese herbal preparation.展开更多
