Effect of Silibinin on cell viability. A) CT26 and B) VERO cells were treated with various concentrations of Silibinin for 24, 48, and 72 h, and their viability was examined by MTT assay. C) Representative images and quantitative analysis of colony formation ability of CT26 treated with 50 μM of Silibinin for 24 h. Data are reported as the mean ± standard error of the mean (n = 8). *P < 0.05 and ***P < 0.001 compared with control
