Cytotoxicity and Modes of Action of the Methanol Extracts of Six Cameroonian Medicinal Plants against Multidrug-Resistant Tumor Cells

Figure 4

Effect of plant extracts and H2O2 (at 50 μM) on the ROS production of CCRF-CEM cells after 24 h treatment. Samples were tested at their 1/4 IC50 (1), 1/2 IC50 (2), IC50 (3), and 2 IC50 (4) values. The IC50 values are 10.57 μg/mL (Gladiolus quartinianus whole plant, GQW), 9.28 μg/mL (Vepris soyauxii leaves, VSL), and 17.32 μg/mL (Anonidium mannii leaves, AML).
