The physical and chemical properties of the date (Phoenix dactylifera L.) fruit seeds from seven date samples (Soukari, Soulag, Barhi, Khulas, Rozaiz, Soughi and Monaif) were evaluated. Energy values of dried and ground seeds were found between 4340 kcal/kg (Barhi cv) and 4795 kcal/kg (Rozaiz cv). Also, while crude oil content of seeds were established between 4.68% (Khulas cv) and 7.96% (Monaif cv), crude protein contents were found at the levels between 3.71% (Soulag cv) and 5.47% (Barhi cv). The antioxidant activity of seeds obtained from different date fruits changed between 78.03 (mg/ml) (Monaif cv) and 79.94 (mg/ml) (Barhi cv). In addition, the total phenol contents of seeds were found between 1.98 mg gallic acid equivalents (GAE)/100 g (Barhi cv) and 4.65 mg GAE/100 g (Soughi cv). The most abundant fatty acids of the date seed oils were oleic, lauric, myristic, palmitic and stearic acids. Ca, Mg, K and P contents of date seeds were found at the high concentrations.
对七种枣（椰枣）果实种子（Soukari、Soulag、Barhi、Khulas、Rozaiz、Soughi 和 Monaif）的物理和化学性质进行了评估。干燥和研磨后的种子的能量值在 4340 kcal/kg（Barhi 品种）至 4795 kcal/kg（Rozaiz 品种）之间。此外，种子的粗油含量在 4.68%（Khulas 品种）至 7.96%（Monaif 品种）之间，粗蛋白含量在 3.71%（Soulag 品种）至 5.47%（Barhi 品种）之间。不同枣果实种子的抗氧化活性在 78.03（mg/ml）（Monaif 品种）和 79.94（mg/ml）（Barhi 品种）之间变化。此外，种子中的总酚含量在 1.98 mg 没食子酸当量（GAE）/100 g（Barhi 品种）和 4.65 mg GAE/100 g（Soughi 品种）之间。枣籽油中最丰富的脂肪酸是油酸、月桂酸、肉豆蔻酸、棕榈酸和硬脂酸。枣种子中的 Ca、Mg、K 和 P 含量很高。
