Fig. 1. Cell viability monitored by the crystal violet assay after 48 h treatment of SK-MEL-28 with a-mangostin, c-mangostin and 8-deoxygartanine. Data are shown as %
viability compared to the untreated control and are presented as means ± SEM of 3 independent experiments. Treatments significantly different from the untreated control at
P < 0.05 are presented as ⁄.
