Abstract :The Pistacia terebinthus L was extracted using liquid and supercritical carbon dioxide together with a co-solvent (ethanol). The effect of different temperatures (30 and 50°C), pressure (250, 300, and 350 bar), extraction time (60 and 120 min), and different percentages of co-solvent (0, 5, and 10%) was investigated. The amount of phenolic compounds, tocopherols, and fatty acid composition was determined. HPLC, UHPLC and GC were used for analysis of phenolic compounds, tocopherols, and fatty acid composition respectively. Quercetin was the main phenolic compound. The oil was rich in unsaturated fatty acids which were between 69.68 – 75.47%. Oleic acid was the predominant unsaturated fatty acid, and the main saturated fatty acid was palmitic acid. Total tocopherol content of the oil was between 13.07-245.3 ppm and the main tocopherol was β-tocopherol. The study showed that the amount of phenolic compounds, fatty acid composition, and tocopherol content were changed according to the parameters.
