The oil from Khaya senegalensis seeds, a dry-zone mahogany plant, was soxhlet extracted with petroleum ether (40-60 degrees C) and characterized by gas chromatograph and infra-red spectroscopy. The fatty acid constituents of the oil were stearic acid (10.41%), palmitic acid (21.39%), oleic acid (64.62%) and unidentifiable acid (3.58%). The presence of unsaturation in the oil was confirmed by infra-red peaks at 1642 and 3003 cm(-1), attributed to olefinic C=C and C-H stretching vibrations, respectively.
