Concentration-dependent effect of crude methanolic plant extracts on HL60 cell lines. The concentration-dependent effect of crude methanolic plant extracts of A. pungu, C. edulis, L. ocymifolia, L. martinicensis and V. verrucosum were evaluated on HL60 cell lines. The cells were incubated with extracts at varying concentrations ranging from 0 to 250 μg/mL. Chlorambucil was used as a positive control at a concentration range of 1.25 to 10 µg/mL. The negative control contained cells and RPMI media only and cell viability was determined after 72 h. The cell viability decreased with an increase in the concentration of the extract
