Abstract
The action of extracts of the stem bark of Spathodea campanulata on Plasmodium berghei berghei in mice has been studied. The blood schizontocidal activity of the extracts was studied
in early and established infections using chloroquine as the reference drug. The prophylactic
action of the extracts was also investigated with pyrimethamine as the standard drug.
The hexane and chloroform extracts of the stem bark showed blood schizontocidal action
in both the 4-Day test and Rane test. The chloroform extract demonstrated some prophylactic
properties while the aqueous extract did not show any significant antimalarial property.
