Fig. 5. Loss of mitochondrial membrane potential was examined by JC-1 dye using flow cytometry after 48 h treatment with a-mangostin, c-mangostin and 8-
deoxygartanine. Data were obtained from 20,000 events and presented as the percentage of cells positive for JC-1 monomer. The values are shown as means ± SEM of 3
independent experiments. Treatments significantly different from the untreated control at P < 0.05 are presented as ⁄.
