Abstract

The petroleum ether extract of Viola websteri Hemsl. (Violaceae) was investigated for its activity against chloroquine-sensitive strains of Plasmodium falciparum using the parasite lactate dehydrogenase assay method. The main antiplasmodial principles, 6-(8′Z-pentadecenyl)-salicylic acid (1) and 6-(8′Z, 11′Z, 14′Z-heptadecatrienyl)-salicylic acid (2), have been isolated from V. websteri for the first time. This is the first report on the antiplasmodial activity of the compounds from V. websteri.
