Extracted ion chromatograms of glycyrrhizin and licoricidin in the Glycyrrhiza uralensis extract. The base peak chromatogram of the glycyrrhiza uralensis extract (0.4 mg/mL) obtained by UPLC-ESI-qTOF in positive ion mode. Expected UPLC-MS peaks of glycyrrhizin and licoricidin were marked as the black circle (●) and the white circle (○), respectively (A). MS (top) and MS2 (middle, bottom) spectra of glycyrrhizin ions. Singly protonated and sodiated glycyrrhizin ions were fragmented to identify glycyrrhizin in the extract (B). MS (top) and MS2 (bottom) spectra of licoricidin in the extract. Singly protonated licoricidin ions were fragmented to identify licoricidin in the extract (C)
