Abstract
Our recent studies on the stem bark of Ploiarium alternifolium Theaceae have yielded the anthraquinone emodin it's derivative ploariquinone A a geranyl anthraquinone and a methoxy bearing anthraquinone. Separation of the triterpenoid-containing fraction gave the phenolic oleanane benzoate. Structural elucidations of these compounds were achieved using H NMR C NMR DEPT COSY and HETCOR experiments while MS gave the molecular masses. The crude extracts were found to be moderately bioactive against the larvae of Aedes aegypti. This paper reports the isolation and identification of these compounds as well as bioassay data for the crude extracts.
