摘要：The fruits of Pistacia lentiscus are a source of a fixed oil used in some forested areas forculinary purposes and in traditional medicines. The aim of this study was to evaluate thelevels of tocopherols, carotenoids and triglycerides in this oil using high-performanceliquid chromatography (HPLC). The results demonstrated the presence of two vitamin Eisomers; α- and γ-tocopherols, at respective concentrations of 119 mg and 23 mg per kgof oil. β-carotene, lutein and zeaxanthin were the principal carotenoid moleculesidentified. β-carotene was the main molecule present, with a level of 6.13 mg/kg oil. Diunsaturatedtriglycerides comprised more than half of the total triglycerides (TAG)present. Dioleopalmitin (OOP), palmitooleolinolein (POL) and triolein (OOO) were theprincipal TAG molecules, at respective percentages of 26%, 17% and 13%. This studyhighlighted the nutritional value of this non-wood forest product and therefore increasesthe possibility of its use by the food industry.
