Oils from seeds of pili (Canarium ovatum Engler), cashew (Anacardium occidentale L.), rambutan (Nephelium lappaceum), mango (Mangifera indica), Kupang (Parchia roxburghii) and alibangbang (Piliostigma malabarecum) were extracted with petroleum ether using a Soxhlet extractor. Crude oil content of the samples follows: pili nut (90.2 percent), cashew nut (43.3 percent), rambutan seeds (32.5 percent), kupang seeds (15.6 percent), alibangbang seeds (16.7 percent) and mango seeds (10.1 percent). The physical and chemical characteristics namely, specific gravity, refractive index, saponification number, iodine number, hydroxyl value, unsaponifiable matter and free fatty acids number were determined. Fatty acid composition of the different oils was determined by gas-liquid chromatography as methyl ethers. Oleic acid is the major fatty acid component of pili nut oil (51.7 percent), cashew nut oil (63.9 percent), alibangbang (22.0 percent) and kupang (42.5 percent). These unsaturated oils may be used as additives for the preparation of tailored fats
