Fig. 3. Antiproliferative effect of rotenolone and tephrosin against human colon cancer cells (HCT 116) after 72 h incubation by the MTT assay. Doxorubicin was used as positive control. Graphs are presented as concentration–effect curves. Insets show inhibition concentration mean (IC50) values along with their respective confidence intervals of 95% (CI95%) and r square (r2) values.
