Evaluation of the Inhibitory Activities of the Extracts of Indonesian Traditional Medicinal Plants against Plasmodium falciparum and Babesia gibsoni

ABSTRACT: Twenty-four kinds of water extracts derived from 22 plants that are traditionally used for the treatment of malaria on Java Island, Indonesia, were screened for their antibabesial and antimalarial activities. Among the extracts, 8 extracts displayed strong anti-malarial activity, with an inhibition range from 89.6 to 100%, and 15 showed strong antibabesial activity, with an inhibition range from 84.2 to 98.1%. The extracts of Achillea millefolium, Baeckea frutenscens, Brucea javanica, Curcuma xanthorrhiza, Strychnos lucida and Swietenia macrophylla showed both strong antibabesial and an timalarial activities. The antimalarial activities paralleled the antibabesial activities, but the converse was not true
