Alpha arbutin as a stable tyrosinase inhibitor Alpha arbutin dose-dependently reduced tyrosinase activity in human melanocytes at concentrations between 0.1 and 1.0 mM without decreasing cell viability, and its inhibitory effect against cellular melanin synthesis was more potent than kojic acid or L-ascorbic acid when compared at a fixed concentration [63]
Moreover, the concentrations of Fe 2+ , Zn 2+ , Mn 2+ , Cu 2+ , and Mg 2+ were 2.322.77, 0.344.78, 0.0460.065, 0.0470.190 and 8.76 mmol/L, respectively, in the chicken liver in accordance with previous studies [62,63,64]
