The crude oil content was 31.1%, while the moisture, fiber, protein, ash and total sugar contents were 4.2%, 24.7%, 28.5%, 4.3%, and 6.9%, respectively. The main fatty acids were linoleic, oleic, palmitic, and stearic acids (61.10%, 18.75%, 10.37% and 9.18%, respectively). The total phenolic content was 28.17 mg·g<sup>–1</sup> oil. Seinat seed oil also contained a good level of tocopherols; of which δ-tocopherol (63.43%) showed the highest content. β-sitosterol was found at 289 mg·100g<sup>–1</sup> oil of total sterols (302 mg·100g<sup>–1</sup>) in the oil. The crude oil showed a good antioxidant activity in four assays including reducing power, β-carotene bleaching inhibition activity, ABTS and DPPH radical scavenging activities. ER -
