ABSTRACT : We prepared supernatants and cell-free extracts of yeasts isolated from wild flowers in Korea, and their antioxidant
activity and inhibitory activities of xanthine oxidase and tyrosinase were investigated. Among them, cell-free extracts of UL40-2 and 121-Z-3 showed significantly high xanthine oxidase inhibitory activity of 46.4%
and 48.3%, respectively. 80-J-1 also showed tyrosinase inhibitory activity of 36.2% in the cell-free extract.
Other antioxidant activities and tyrosinase inhibitory activities were not detected or were below 20%. Maximal production of the
xanthine oxidase inhibitors were observed when UL40-2 and 121-Z-3 were
cultured in the yeast extract-peptone-dextrose media at 30ºC for 24 hour, respectively.
