ABSTRACT
Two pentacyclic triterpenes α-amyrin acetate and lupeol were isolated from the n-hexane soluble fraction of the aqueous ethanol extract of the aerial parts of Glossonema boveanum, a plant used in traditional medicine for the treatment of epilepsy and stimulation of lactation using a combination of silica gel column chromatography and preparative TLC. The structures of these compounds were elucidated using NMR spectroscopic analysis (1D& 2D) and by comparison with reported data. This is the first report of isolation of these compounds from this plant and its genus.
