Recebido em 28/9/06; aceito em 27/4/07; publicado na web em 25/10/07 CHEMICAL CONSTITUENTS FROM BARK OF Cenostigma macrophyllum: CHOLESTEROL OCCURRENCE. Phytochemical investigation of the bark of Cenostigma macrophyllum (Leguminosae-Caesapinioideae) resulted in the isolation and identification of valoneic acid dilactone, ellagic acid, lupeol, alkyl ferulate, four free sterols (cholesterol, campesterol, stigmasterol and sitosterol), a mixture of sitosteryl ester derivatives of fatty acids, sitosterol-3-O-β-D-glucopyranoside, stigmasterol-3-O-β-D-glucopyranoside and saturated and unsaturated fatty acids. The structures of the isolated compounds were identified by 1 H and 13 C NMR spectral analysis and comparison with literature data. The mixtures of 3-β-hydroxysterols and fatty acids were analysed by GC/MS.
