  • Objectives : Genetic analysis and taste pattern were performed to identify species between Glycyrrhiza uralensis and G. glabra which are officially listed in Korean Pharmacopoeia IX as origin of Gamcho(g$\={a}$nc$\v{a}$o, licorice root, Glycyrrhizae Radix et Rhizoma). Methods : Genetic analysis showed that identification between two species was done by comparing base sequence of ITS(intergenic transcribed spacer) and trnH-psbA regions from eleven Gamchoes sold in market. There was different taste pattern using by taste sensor in Glycyrrhiza uralensis and G. glabra. Results : Genetic analysis showed that six Gamchoes from China were identified as Glycyrrhiza uralensis and five Gamchoes from Uzbekistan were G. glabra. From the results of taste pattern, sourness and astringency of Glycyrrhiza uralensis from China were significantly higher than G. glabra from Uzbekistan, and aftertaste of astringency, aftertaste of umami, and saltiness of Glycyrrhiza uralensis were signicantly low as compared to G. glabra. There is no significant difference between two species in terms of bitterness, aftertaste of bitterness, and umami. Conclusions : Taken together, Glycyrrhiza uralensis from China and G. glabra from Uzbekistan were identified by taste sensor, and this technic could be applied to establishment of taste pattern marker for identification of different species located in various regions.
