The effects of crude methanolic plant extracts on Jurkat T cell lines. Crude methanolic plant extracts were tested for their antiproliferative effect on Jurkat T cell line at a concentration of 250 µg/mL. Chlorambucil was used as a positive control at a concentration of 10 μg/mL. The negative control contained cells and RPMI media only. The cells were incubated with test solutions and cell viability was determined after 72 h. The values are for the mean ± SD for n = 3. All treatments were compared to cells only to determine the level of significance. The level of significance is denoted as follows: **** P < 0.0001. A. pungu, C. edulis, F. indica, L. ocymifolia, L.martinicensis, P. kalachariensis, S. spinosa and V. verrucosum, significantly inhibited the proliferation of Jurkat T cell line and V. verrucosum had the greatest potency
