Antiplasmodial and cytotoxicity activities of some selected plants used by the Maasai community, Kenya

AbstractMalaria has continued to be a major global public health problem and a health concern in most of African countries. An estimated 350–500million cases of malaria each year result in about one million deaths, mainly children under five. The rate of malaria infection is increasing rapidly partly due to drug resistance by the Plasmodium falciparum. The cost of the current drugs is prohibitive to the poor. There is therefore urgent need to identify new antimalarial agents that are effective, safe and affordable. In our continuous search for these new antimalarial compounds, extracts from five medicinal plants from the Maasai community in Kenya were tested against P. falciparum (D6; chloroquine sensitive and W2; chloroquine resistant strains). Of the tested total plant extracts, 5 crude extracts showed good antiplasmodial activity against D6 strain of P. falciparum with IC50 values lower or equal to 14.3μg/ml, 2 were moderately active with IC50 values in between 26.6 and
