- Two different melanoma cell lines (A2058 and HT168-M1) and normal fibroblast cells (MRC-5) were applied as model cells and were incubated with the anthraquinones for 6 h
- The ‘Inhibition index’ is expressed as a percentage of the control. Data shown in the table represent mathematical averages of six parallels and ± S.D. values
- The level of significance is shown as follows: * p < 0.05; *** p < 0.001
