: The quality of phytoestrogenic licorice was studied by using both chemical and biological fingerprints. A recombinant yeast strain that consists of an estrogen responsive element linked with a reporter gene (ADE2) and a transformed human estrogen receptor–containing plasmid was used for screening and evaluation of estrogenic activity in licorice. Several estrogen-like components in licorice were screened, and licoisoflavone B and formononetin were identified. Licorice extracted with 70% ethanol showed 5 different patterns of chemical fingerprints (LR-A, LR-E, LR-F, LR-H, LR-K), as identified by chromatographic analysis. Among these, LR-E exhibited the strongest estrogenic activity, whereas LR-A, LR-F, and LR-H were in the middle, and LR-K had the weakest activity.
