Abstract: Napoleonaea imperialis P. Beauv (Lecythidaceae) is a medicinal plant commonly found in South-Eastern Nigeria. The ripe fruits were extracted and partitioned into hexane, chloroform, n-butanol and aqueous fractions. These fractions were earlier tested and shown to possess anti-bacterial activities. The chloroform extract was chromatographed and purified to give compounds 1-5 whose structures were elucidated using ir, 1H and 13C-nmr as methyl-1,3,5-triene-tricyclopentadecanoate (1); 5-methyl-5-toluyl-3,4,6-trihydropyran-2-one (2, napoleonapyran-2-one); 4-ethoxy-bicyclodecylbenzoate (3); 3β-O-[β-D-glucopyranosyl(1→2)][β-D-glucopyranosyl(1→4)][β-D-glucopyranosyl]-16α,22α,24,28-tetrahydroxy-21-β-O-angeloxyolean-12-ene-29-al (4, napoleon aside -B) and 3-O-[β-D-glucopyranosyl]-1,4–dimethyl-2,4,5,10-tetrahydroxy–bicyclodecane (5).
