Abstract: | In the current study, we examined the antioxidant and skin-whitening properties of Prunus mume extract (PME). The ability of PME to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals was investigated in vitro. At a concentration of 1000 μg/mL, PME neutralized >45% free radical activity. Cell viability assessment with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay revealed that at concentrations <1500 μg/mL, PME does not exert cytotoxic effects on murine B16 melanoma (B16) cells. Morphological analysis disclosed that melanin production is inhibited in B16 cells treated with 250 nM α-melanocyte-stimulating hormone (α-MSH) and PME. We conclude that fruit extracts of P. mume exert a skin-whitening effect by inhibiting melanin production via regulation of melanogenesis-associated protein expression in melanocytes. |
