The effects of EJEE on cell viability (a) and melanin contents (b). The cells were treated different concentrations (0.01, 0.05, 0.1, 0.5, and 1.0%) of EJEE for 24 h. The basal values (control) were obtained in the absence of EJEE. **p < 0.01 as compared to the control group (a). The cells were treated with α-MSH (100 nM) and different concentrations (0.01, 0.05, and 0.1%) of EJEE for 72 h. Arbutin (10 mM) was used as a positive control. The values represent as the means ± SD of three independent experiments. *p < 0.05 as compared to the α-MSH-treated group (b)
