The seed oil of 18 leading varieties of date fruits cultivated in the UAE (Khalas, Barhe, Lulu, Shikat alkahlas, Sokkery, Bomaan, Sagay, Shishi, Maghool, Sultana, Fard, Maktoomi, Naptit Saif, Jabri, Khodary, Dabbas, Raziz and Shabebe) were analyzed and compared for fat soluble vitamins, carotenoids and fatty acid profiles. Results showed significant variations among the different varieties for their fatty acid, carotenoid, vitamin E, and vitamin K content. Results also revealed that the major fatty acid in date seed oil is oleic acid (49.50%), followed by myristic acid (14.52%) and linoleic acid (10.23%). Pentadecanoic, palmitic, heptadecanoic, stearic, arachidic, behenic, palmitoleic, cis10-heptadecenoic, cis11-eicosenic, linolenic, cis11,14-eicosadienoic, cis-11,14,17-eicosatrienoic were also found in date seed oil. β-Carotene was found to be the most occurring carotenoid in all of the 18 date seed oil varieties and ranged between 1.18mg and 2.68mg/100g. Moreover, the 18 date seed oils depicted considerable concentrations of vitamin E (ranged between 1.01mg and 1.86mg/100g α-tocopherol; 0.61mg and 0.98mg/100g α-tocopheryl acetate; 0.40mg and 0.70mg/100g γ-tocopherol), and vitamin K1 (ranged between 0.10mg and 0.19mg/100g). The results obtained indicate a strong potential for date seed oil to be used as a source of essential fatty acids in healthy edible oil, as well as in cosmetics and pharmaceutical applications.
