The seed of Entandrophragma angolense yielded 59% oil (w/w) on extraction with n-hexane. Methylation and gas chromatography-mass spectrometry (GC-MS) analysis of the methylated seed oil of E. angolense gave 11-octadecanoic acid methyl ester as major component (43.2%). Other fatty acid methyl esters (FAMEs) detected were hexadecanoic acid methyl ester, ricinoleic acid methyl ester, stearic acid methyl ester and eicosadienoic acid methyl ester. Preliminary antimicrobial evaluation of this seed oil showed activity against Salmonella gallinallum and Klebseilla pneumonia.
Key words: Entandrophragma angolense, octadecanoic, Salmonella gallinallum,Klebseilla pneumonia.
