Cytotoxicity of the natural compounds and extracts. a Cytotoxicity assays were performed with the four anti-malarial compounds. 293T cells were incubated with different concentrations of test compounds for 96 h (see “Methods”). The authors observed high cell viability in the presence of all four compounds at concentrations of < 1 µM. b Cytotoxicity assays were performed with the two anti-malarial extracts. 293T cells were incubated with various concentrations of the test extracts for 96 h (see “Methods”). The authors observed high cell viability in the presence of both extracts at concentrations of < 1 µg/ml
