ABSTRACT
Viability and suitability of any oil type largely depend on its physical, chemical properties, fatty acid composition content as well as the origin of a seed plant. Gas chromatography was used to determine the composition of fatty acid content, and the physiochemical properties such as saponification value, viscosity, iodine value, peroxide value, acidity, refractive index were determined. The oil was found to contain high levels of unsaturated fatty acids of oleic (41.30 ? 1.50) linoleic (31.40 ? 1.20) acids, palmitic (19.50 ? 0.80) and stearic (6.80 ? 0.60) acids. This paper explores the composition of fatty acids content and its characteristic of physiochemical properties of Jatropha curcas oil from Sokoto and Zamfara states in Nigeria and the Niger Republic. The oils were comparable with mineral oils. The oils of Jatropha curcas oil were compared concerning three locations, with no significant difference (P < 0.05). The aforementioned physicochemical properties aid in the determination of quality oil of jatropha curcas. The results showed that Jatropha curcas oil possessed better properties that are viable and suitable for industrial applications. Considering these results, Jatropha curcas can be tailored for the production of oil of industrial applications like (biodiesel, Insulant, lubricant, painting, soap, and insecticides, etc.)
