Ursolic acid is recognized for various effects such as anti-cancer, antioxidant, and anti-inflammatory activity. In this study, we confirmed the anti-cancer effect of ursolic acid on human melanoma cancer cells, A375SM and A375P. Survival rate of the melanoma cells was confirmed by MTT assay and the proliferation rate was confirmed by wound healing assay. The rate of apoptotic bodies was confirmed by DAPI staining, and apoptosis rate was confirmed by flow cytometry. The induction of apoptosis protein was examined by western blotting according to the concentration of ursolic acid in melanoma cells. The survival and proliferation rates of melanoma cells were decreased according to the treatment concentrations of ursolic acid. DAPI staining showed that chromosomal condensation of melanoma cells was increased with increasing concentrations of ursolic acid, and increased apoptosis rate of melanoma cells by ursolic acid was confirmed by flow cytometry. We also confirmed by western blotting that cleaved-PARP and Bax were increased and Bcl-2 was decreased at $12{\mu}M$ concentration of uricolic acid in melanoma cells. This study was carried out at low concentrations of ursolic acid, 0 to $20{\mu}M$, and analyzed 24 h after treatment. As a result of this study, it is thought that ursolic acid has the anti-cancer effect through the regulation of apoptosis-related proteins in melanoma cells A375SM and A375P.
