Anti-melanogenic effect of loliolide. (a) Measurement of cell viability by MTT assay in loliolide-treated B16F10 cells. (b) Measurement of melanin secretion by melanin secretion assay in B16F10 cells treated with α-MSH and loliolide. (c) Measurement of melanin production by melanin content assay in B16F10 cells after treatment with α-MSH and loliolide. (d) Western blot analysis of the expression of MC1R signaling pathway proteins in α-MSH- and/or loliolide-treated B16F10 cells. Statistical significance (b,c) was evaluated using the Kruskal–Wallis/Mann–Whitney test. ## p < 0.05 compared with normal group and ** p < 0.01 compared with control.
