Concentration-dependent effect of crude methanolic plant extracts on Jurkat T 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 Jurkat T cell lines. The cells were incubated with crude methanolic plant extracts at varying concentrations ranging from 0 to 250 μg/mL and cell viability was determined after 72 h. Chlorambucil was used as a positive control at a concentration of 1.25 to 10 μg/mL. The negative control contained cells and RPMI media only. The cell viability decreased with an increase in the concentration of the extract
