Against the scourge of malaria in Africa and the development of chemo-resistance, discovering new natural cures is a major concern for many researchers. As a consequence, the present study was carried out in order, first, to identify the phytochemical compounds, and second, to assess the antiplasmodial activity, of three medicinal plants extracts, selected from an ethno-botany survey conducted in Senegal. The parts of the plants used were Strychnos spinosa (Strychnaceae) leaves and stems, Combretum glutinosum (Combretaceae) barks, and the whole aerial part of Pennisetum polystachion (Poaceae). Among these plants, the hydromethanolic extracts of Strychnos spinosa stems showed the most important activity against Plasmodium falciparum strains, with a IC50 of 15 μg/ml, followed by the leaves chlorophormic extracts and the ethyl acetate extracts of Pennisetum polystachion, with respective IC50 of 20 μg/ml and 21 μg/ml. Combretum glutinosum extracts showed the least important activity, in all tests.

Information collected from nine (09) traditional healers in the Moronou village in the Department of Toumodi revealed that Anthocleista djanlonensis is regularly used by the population for primary health care in the processing of malaria. Evaluation of the In vitro antiplasmodial activity showed that the aqueous extracts inhibit growth of clinical isolates and chloroquinoresistant strains (K1) with IC50 of 8.29 µg/mL and 10.23 µg/mL while the ethanolic extracts had IC50 of 37.65 µg/mL and 46.07 µg/mL on the same strains respectively. Results of the In vitro antimalarial bioassay showed that aqueous extracts have promising antiplasmodial effects on clinical isolates and on Plasmodium falciparum multidrug resistant K1 strain (3 µg/mL <IC50 <15 µg/mL). Phytochemical screening revealed that the extracts contain mainly alkaloids, polyphenols, polyterpenes and flavonoids

Developing countries, where malaria is one of the most prevalent diseases, still rely on traditional medicine as a source for the treatment of this disease. In the present study, six selected plants (Acalypha fruticosa,Azadirachta indica,Cissus rotundifolia,Echium rauwalfii,Dendrosicyos socotranaandBoswellia elongata) commonly used in Yemen by traditional healers for the treatment of malaria as well as other diseases, were collected from different localities of Yemen, dried and extracted with methanol and water successfully. The antiplasmodial activity of the extracts was evaluated against fresh clinical isolates ofPlasmodium falciparum. The selectivity parameters to evaluate the efficacy of these medicinal plants were measured byin vitromicro test (Mark III) according to World Health Organization (WHO) 1996 & WHO 2001 protocols of antimalarial drug tests. Among the investigated 12 extracts, three were found to have significant antiplasmodial activity with IC50values less than 4 µg/ml, namely the water extracts ofA. fruticosa,A. indicaandD. socotrana. Six extracts showed moderate activity with IC50values ranging from 10 to 30 µg/ml and three appeared to be inactive with IC50values more than 30 µg/ml. In addition, preliminary phytochemical screening of the methanolic and aqueous extracts indicated the presence of saponins, tannins, flavonoids, terpenoids, polysaccharides and peptides.
