The anti-proliferative activity of Matrine in four carcinoma cell lines and one normal human cell line. Cells were incubated with Matrine as concentrations indicated for 48 h before 3-(4,5-Dimethyl-thiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) was performed. All experiments were performed at least thrice and independently. Significant differences from untreated control were indicated as *p < 0.05; **p < 0.01; ***p < 0.001.
