Inhibition of tyrosinase activity by A. microcarpus flowers extract. a Lineweaver-Burk plot for inhibition of ethanol extract on mushroom tyrosinase activity using l-DOPA as substrate. Reaction mixtures contained mushroom tyrosinase in 25 mM phosphate buffer (pH 6.8) and l-DOPA, in the absence or presence of extract at different extract concentrations. b Replot of the 1 ⁄Vmax values versus extract concentration
