Fig. 2From: Anti-malarial activity of the alkaloid, heptaphylline, and the furanocoumarin, imperatorin, from Clausena anisata against human Plasmodium falciparum malaria parasites: ex vivo trophozoitocidal, schizonticidal and gametocytocidal approachEx vivo inhibition of: trophozoite (A–C); schizont (D–F) and gametocyte (G–I) stages of human P. falciparum by imperatorin, heptaphylline and artesunate. The shape of F reversed because the % parasitaemia inhibition was calculated from the highest to the lowest concentration instead of the reverse. However, the IC50 value is not affected by the shape of the graphBack to article page
