Physiological properties of root and stolon of Gamcho (Licorice, Glycyrrhiza uralensis Fischer) were compared following irradiation at 20 kGy. The root and stolon of Gamcho were extracted with 70% ethanol, irradiated and stored in a 4℃ refrigerator. Irradiation induced color changes, electron donating ability (EDA), and tyrosinase inhibition effect (TIE) were investigated. The color of the non-irradiated stolon extract was darker than the non-irradiated root extract (p＜0.05), but irradiation eliminated color differences between stolon and root extracts. Generally, irradiation did not affect EDA and TIE of either of the extracts. However, EDA and TIE were higher in stolon extract than in root extract, when the higher dilution factor was considered. These results indicate that the stolon of Gamcho, which is mostly wasted, is a valuable source of phytochemicals with greater EDA and TIE activities than Gamcho root.
