The oil content of saturated and unsaturated fatty acids with some physico-chemical properties and nutrients were investigated in oil produced from seeds of six important date palm cultivars and one seed strain present in Saudi Arabia. The results indicated that the oil extracted from six seed cultivars of date palm ranged from 6.73-10.89% w/w oil. The refractive index of date seeds oil was found to be between 1.4574 to 1.4615. The iodine values, acid values and saponification values were in the range of 74.2-86.6 g iodine 100g-1; 2.50-2.58 mg KOH g-1 and 0.206-0.217 mg KOH g-1, respectively. Lauric acid, Myristic acid, Palmitic acid C15, Palmitic acid C16,? Stearic acid, Arachidic acid and Behenic acid of date seeds oil contents were found between? 8.67- 49.27; 7.01-15.43; 0-0.57; 4.82-18.09; 1.02-7.86; 0-0.08; and? 0-0.15 % w/w, in that order. Omega-6 and Omega-9 of date seeds oil were found between 7.31-17.87 and 52.12-58.78%, respectively. Khalas ,Barhy cvs. and seed strain gave highest K and Ca, Na and Fe, Mg as? compared with other studied cultivars. ??
