    • 38 Briefly, mushroom tyrosinase purchased from Sigma-Aldrich was used in this experiment. First, 0.1 mL of the DMSO solution of the inhibitor was mixed with 0.3 mL of a 5.0 mM of l-DOPA aqueous solution, 0.6 mL of 0.25 M sodium phosphate buffer (pH 6.8) and 1.9 mL of water, incubated at 30 C for 5 min. Then, 0.1 mL of enzyme solution was added to the mixture. This solution was immediately monitored for the formation of dopachrome by measuring the linear increase in optical density (475 nm) at 30 C.
