title: Effect of growing area on tocopherols, carotenoids and fatty acid composition of Pistacia lentiscus edible oil.
abstract: In this investigation, we aim to study, for the first time, the effect of the growing area on tocopherols, carotenoids and fatty acid content of Pistacia lentiscus fixed oil. Fruits were harvested from eight different sites located in the north and the centre of Tunisia. Tocopherols, carotenoids and fatty acid content of the fixed oils were determined. The highest carotenoid content was exhibited by Feija oil (10.57 mg/kg of oil). Oueslatia and Tabarka oils displayed the highest α-tocopherol content (96.79 and 92.79 mg/kg of oil, respectively). Three major fatty acids were determined: oleic, palmitic and linoleic acids. Oleic acid was the main fatty acid presenting more than 50% of the total fatty acid content. Kebouche oil presented the highest oleic acid content (55.66%). All these results highlight the richness of carotenoids, tocopherols and unsaturated fatty acids in P. lentiscus seed oil and underscore the nutritional value of this natural product.
