Tyrosinase Inhibitory Activity of 80 Plant Extracts (II)

초록

The purpose of this study was to evaluate tyrosinase inhibitory activity of plant extracts for cosmeticuse. When 80 plant extracts were tested, the methanol extracts of Allium thunbergi, Asparagus oligoclonos, Ixerisdentate, Salvia plebeia, Sophora flavescens and Sophora japonica showed more than 30% inhibition of mush-room tyrosinase activity at 100 g/mL. Although less active than the reference compound, kojic acid (IC50=7.016.3 g/mL), these plant extracts may be used as tyrosinase inhibitors in cosmetics.Keywords tyrosinase, plant, skin whitening, Salvia plebeia, Sophora flavescens.
