Seed Oil 2020-02-25T14:15:36+00:00 Abeer A. Idris Azhari H. Nour azharyhamid@yahoo.com Mahmoud M. Ali Ibrahim Y. Erwa Omer A. Omer Ishag Abdurahman H. Nour <p><em>Ocimum basilicum</em> has been widely used in traditional medicine. Rural communities have used fixed oils for variety purposes since a long time ago. They used for cosmetic applications, fuel, medicine and food. The aim of this study was to characterize the physicochemical properties and fatty acid composition of <em>O. basilicum</em> seed oil. Lipids were determined by continuous extraction in a Soxhlet apparatus for 6 hours using hexane as solvent. The physicochemical properties of the oil were assessed by standard and established methods. The fatty acids composition of the seed oil was determined by GC-MS. The Pale yellow with camphor odor oil extracted from the seed has the following properties: yield, 18.01%; freezing point, -2°C; melting point, 5°C; boiling point, 215°C; refractive index (25°C), 1.48532; iodine value, 108.6 g/100 g of oil; peroxide value, 4.6 meq. O<sub>2</sub>/kg of oil; free fatty acids, 0.20%; acid value, 4.0 mg of KOH/g of oil; saponification value, 164.2 mg KOH/g of oil; unsaponifiable matter, 1.6; moisture and volatile value, 4.97 (wt%); density, 0.91372 g/cm<sup>3</sup>; viscosity, 10.29 mm<sup>2</sup>/s; specific gravity, 0.9210. Fatty acids composition showed that linolenic- (43.92%) was the major fatty acid and followed by linoleic- (32.18%), palmitic- (13.38%), stearic- (6.55%), palmitoleic- (0.78%), arachidic- (0.72%), anteisomargaric- (0.45%), nonadecylic- (0.28%), gondoic- (0.27%), margaric- (0.20%), behenic- (0.17%), heneicosylic- (0.14%), lignoceric- (0.13%) and myristic acid (0.11%). Therefore, recommended that more and advanced investigations should be undertaken for this abundant oil as natural source for many industrial applications, especially, for applications that require acids like linolenic and linoleic.</p> 2020-01-17T00:00:00+00:00 ##submission.copyrightStatement##
