This formation of adducts with MBTH has been used as method to characterize many monophenols and o-diphenols [40,41,44,45]. The numerous studies on and -arbutin as inhibitors of tyrosinase are sometimes contradictory. Action of tyrosinase on arbutins in the presence of hydrogen peroxide. However, taking into account the action mechanism of the enzyme on monophenols, the action of tyrosinase can be facilitated in the presence of an o-diphenol or H2O2, which transform Em into Eox. Total oxygen consumption test in the presence of L-dopa and different concentrations of -arbutin (mM): a) 0, b) 2, c) 5 and d) 20.
