Cell viability of HCT 116 cells after exposure of acetone extract from stem bark of C. odontophyllum. Cell survival is expressed as a percentage relative to the negative control (untreated). Acetone extract from stem bark of C. odontophyllum at concentration ranging from 0 – 200 μg/ml exhibited cytotoxic activity against HCT 116 cells at 24, 48 and 72 h of treatment exposure. Each point represents the mean of triplicates from 3 different experiments ± S.E.M
