The inhibitory effects of lucidadiol on the viability of B16 melanoma cells. A The structure of lucidadiol. B, C Cells were treated with lucidadiol at various concentrations for 24 h or treated with 15 µM for 0, 12, 24, and 48 h. Cell viability was measured using the MTT assay. D, E Cell viability was determined via trypan blue and crystal violet staining, after treatment with/without lucidadiol for 24 and 48 h. scale bar = 100 µm. F The colonies were stained with crystal violet and analyzed using a microplate reader. The data are presented as the mean ± SD. *p < 0.05 when compared with the control group
