Abstract

Some properties of kojic acid glucoside were compared with those of kojic acid. As for antibacterial activity and tyrosinase inhibitory activity, those of kojic acid glucoside were less effective than those of kojic acid. As for chelation with Cu2+, Cd2+, and Co2+, the overall stability constants of kojic acid glucoside and kojic acid were very similar.Furthermore, the stabilities of kojic acid glucoside and kojic acid against light and heat were investigated. Kojic acid glucoside were more stable than kojic acid against light and heat about 2.5 and 5 times, respectively.
