This study evaluated the tyrosinase-inhibition activities of three extracts; methanol, acetone and dichloromethane of Datura metel leaves. The bioactive components were extracted and then evaluated for their inhibitory effect in vitro on mushroom tyrosinase, using a colorimetric procedure. The Methanolic extract of the plant leaf had the highest inhibition of tyrosinase conversion of substrate L-DOPA with 72.14% inhibition at peak concentration of 400 µg/ml considered unlike their respective acetone (51.08%) and dichloromethane (65.57%) extracts. All the Datura metel extracts had below 50% inhibition between concentrations of 3.1 µg/ml to 200 µg/ml except the methanolic extract which had 53.46% inhibition at 200 µg/ml. Although, there was a steady increase in tyrosinase inhibition for all plant extracts, however none of the plants extracts inhibition exceeded kojic acids inhibition at all concentrations considered.
