    In Vitro Antiplasmodial Activities of Crude Extracts ofCarissa edulis, Azadirachta indica, Cassia siamea andHarrisonia abyssinica against Plasmodium falciparum

    The emerging resistance of Plasmodium falciparum to chloroquineand sulfadoxine pyrimethamine drugs in Kenya has necessitated the need to look for new more effective antimalarial drugs. This study investigated the in vitro antiplasmodial activities of methanolic and aqueous crude extracts of Carissa edulis, Azadirachta indica, Cassia siamea and Harrisonia abyssinica on Plasmodium falciparum strains. Drug assays were conducted using SYBR Green 1 dye. Two Reference Plasmodium falciparum strains, 3D7 and W2 were assayed against two anti-malarial conventionaldrugs and crude extracts of Carissa edulis, Azadirachta indica, Cassia siamea and Harrisonia abyssinica to generate 50% inhibitory concentrations of chloroquine, mefloquine, methanolic and aqueous extracts. These extracts have potential for antimalarial activities thatcan be used to develop pure compounds for prospective antimalarial molecules for therapeutic uses. Methanolic and aqueous extracts of Carissa edulis, Azadirachta indica, Cassia siamea and Harrisonia abyssinica demonstrated in vitro antiplasmodial effect on the two Plasmodium falciparum strains. These findings support the hypothesis that these plants have antiplasmodial activities against Plasmodium falciparum strains through the active phytochemicals found in them. The extracts f
