Abstract
Eight compounds were isolated from the roots of Glycyrrhiza glabra by the tyrosinase inhibitory activity guided fractionation, and their structures were identified as liquiritigenin (1), isoliquiritigenin (2), isoliquiritigenin-2-O-methyl ether (3), liquiritin (4), isoliquiritin (5), ononin (6), glycycoumarin (7), glycyrol (8) by analysis of spectral data. Compound 3 exhibited the most potent inhibitory effect on mushroom tyrosinase activity (IC50, 47 M).
