Keywords:Abutilon pannosum, Albizia lebbek, Cassia obtusifolia, Cassia occidentalis, Fatty acid, Ipomea indica, Mitracarpus villous, Sesamum alatum, Tocopherol
Seven oils, obtained from seven Sudanese oil bearing sources that are Albizia lebbek Oil (ALO), Cassia obtusifolia Oil (COO), Cassia occidentalis Oil (CCO), Abutilon pannosum Oil (APO), Mitracarpus villous Oil (MVO), Ipomea indica Oil (IIO) and Sesamum alatum Oil (SAO), were investigated. The seeds were collected in Sudan from Ghibaish, North Kordofan state. In addition to the oil content, the fatty acid was determined by capillary gas chromatography and the tocopherols were evaluated by highperformance liquid chromatography. The oil content of the seven seeds amounted to 12.8, 7.0, 3.2, 7.1, 11.5, 8.8, and 21.3%, respectively.The oils contained 16.4, 20.0, 14.3, 16.8, 19.4, 19.9 and 10.9 % palmitic acid and 21.0, 24.4, 22.1, 10.9, 27.7, 34.0, 45.1 % oleic acid, and 43.8, 38.2, 45.0, 63.9, 34.6, 33.5, 36.3 % linoleic acid and traces of linolenic acid, respectively.The tocopherol content of these oils amounted to 85.6, 48.2, 32.7, 163.5, 52.5, 30.9, and 26.4 mg/100 g oil, respectively. Alpha-tocopherol was the predominant tocopherol in the oil of Albizia lebbek, Cassia obtusifolia, Cassia occidentalis, and Abutilon pannosum, while gamma-tocopherol was the predominant tocopherol in the oil of Mitracarpus villous, Ipomea indica and Sesamum alatum.
