Composition and anti-plasmodial activities of essential oils from some Cameroonian medicinal plants.

In a search for new plant-derived biologically active compounds against malaria parasites, five essential oils extracted from the Cameroonian plants Xylopia phloiodora, Pachypodanthium confine, Antidesma laciniatum, Xylopia aethiopica, and Hexalobus crispiflorus were evaluated in regard to their anti-plasmodial activity against the W2 strain of Plasmodium falciparum. The oils were obtained from the plants with 0.12, 0.13, 0.18, 0.6 and 0.1% yields (relatively to dried material weight) respectively. Analysis by gas chromatography and mass spectrometry identified mainly terpenoids, among which alpha-copaene, gamma-cadinene, delta-cadinene, alpha-cadinol, spathulenol and caryophyllene oxide were most commonly found. The five oils were active against Plasmodium falciparum in culture. The most effective was the oil of Hexalobus crispiflorus, with an IC50 of 2 microg/ml.[1]
