Rapid identification of chemical constituents responsible for defined bioactivities from traditional Chinese medicines (TCMs) is a great challenge. A strategy for rapid identification of the chemical ingredients from the extracts of the rhizoma of Curcuma kwangsiensis with supercritical fluid extraction (SFE) was proposed using ultra-performance convergence chromatography coupled with a quadrupole time-of-flight mass spectrometry (UPC2-QTOF-MS) combined with UNIFI library. In this study, a total of 47 chemical compounds which were separated in 7 min were tentatively identified, including 42 sesquiterpenes. There were 37 chemical constituents in 8 groups of isomers in the analysis. The strategy which can rapidly, effectively, and comprehensively screen and identify components from TCMs has potential application in TCMs analysis as an alternative method besides UPLC-QTOF-MS and GC-MS.
