The effect of A. squamosa extracts on the proliferation of colon cancer cell lines as determined by using MTT and nucleus staining assays. The cell viability of Lovo cells (a) and HCT-116 cells (b) in the MTT assay (n = 5). c Photomicrographs of colon cell lines treated with three different concentrations of methanolic extract of A. squamosa leaves. The control comprised cells treated with DMSO (*p < 0.05, **p < 0.005)
