Combinatory effects of curcumin and carnosic acid on the mitochondrial membrane potential. Cells were treated with 7 μM CUR and 5 μM CA, alone and in combination (CUR + CA). The data were recorded at 5 min (0 h), 4 h and 24 h after the addition of DMSO or polyphenols. Data are presented as mean ± SEM (n = 3) relative to DMSO-treated cells. Statistically significant differences for CUR, CA or CUR + CA vs. DMSO (* p < 0.05; ** p < 0.01 and *** p < 0.001) and for CUR and CA vs. CUR + CA (# p < 0.05; ## p < 0.01 and ### p < 0.001). § p < 0.05 and §§ p < 0.01, significant difference between the indicated groups (Student’s t-test).
