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 Kuraishia capsulata UL40-2 and Sporobolomyces ruberrimus 121-Z-3 showed significantly high xanthine oxidase inhibitory activity of 46.4% and 48.3%, respectively. Starmerella bombicola 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 Kuraishia capsulate UL40-2 and Sporobolomyces ruberrimus 121-Z-3 were cultured in the yeast extract-peptone-dextrose media at 30oC for 24 hour, respectively.
