In this study, the oil amounts, bioactive components, fatty acid profiles and element quantities of the date kernels (Osailah, Rothanh Qassim, Rushudiah, Nabtat-Ali, Sbakah) were determined. The oil quantities of the date seeds were altered to be between 3.50 (Osailah) and 5.55% (Nabtat-Ali). The total phenolic quantities of the seeds were assigned to be between 330.83 (Rothanh Qassim) to 365.42 mg GAE/100 g (Osailah) while antioxidant activities of date seeds are assessed to be between 13.89 (Rothanh Qassim) and 38.74% (Nabtat-Ali). The total flavonoid quantities of the date seeds were displayed to be between 4824.83 (Osailah) and 9133.17 mg/100 g (Sbakah). The (+)- Catechin and 1,2-dihydroxy benzene quantities of the date seeds were established to be between 75.01 (Rothanh Qassim) and 186.02 mg/100 g (Sbakah) to 67.43 (Rothanh Qassim) and 199.89 mg/100 g (Sbakah), respectively. Oleic acid amounts of the seed oils were altered to be between 45.89 (Rothanh Qassim) and 52.55% (Nabtat-Ali). K, P, S, Ca and Mg were the key minerals of the date seeds. Considering the bioactive components, polyphenol contents, fatty acid composition and mineral content of date kernels, it is thought that date kernel powders can be added to some foods as a food supplement.
