Effect of myricetin 3-O-β-d-galactopyranoside (M3G), vehicle (10% DMSO) and UVA on the viability of HaCaT keratinocytes and human dermal fibroblasts (HDFs). HaCaT keratinocytes and HDFs were treated with given final concentrations of M3G (A) and equivalent amount of DMSO (B) and incubated for 24 h. Viability of the cells were then quantified by MTT assay. (C) HaCaT keratinocytes and HDFs were irradiated with UVA (0–10 J/cm²) and incubated for 24 h and the viability of the cells were quantified by MTT assay. Relative cell viability was expressed as the mean ± SD (n = 3) (% of untreated control) of three independent experiments run in triplicate. * p < 0.05 compared to untreated control group.
