The ethyl acetate and methanol extracts of experimental
plants were evaluated for their antimalarial activity against
P. falciparum strains 3D7, Dd2, and INDO. For drug
screening, SYBR green I-based fluorescence assay was
setup as described (Smilkstein et al. 2004). Sorbitol
synchronized parasites were incubated under normal culture
conditions at 2% hematocrit and 1% parasitemia in the
absence or presence of increasing concentrations of plant
extracts. CQ and artemisinin were used as positive controls,
