Abstract
Wild natural species could offer an important issue for the sustainable development and environ- mental protection. Pistacia atlantica is an interesting wild species wide spreading in arid land in Tunisia. Recent works focused on the use of this species as rootstock for pistachio cultivation and the investigation of oil quality of seeds. This study aims to evaluate three methods of oil extraction from Pistacia atlantica seeds. Seed oil was extracted by pressing, supercritical CO2 and organic solvent and respective oil qualities were determined. Results showed that the supercritical CO2 method is the most efficient with an extraction rate of 25 per cent compared to extraction by pressing (5.3 per cent) or by solvent (7.9 per cent). The extracted oil was rich in unsaturated fatty acids with similar acid composition between the three extraction methods. However, the supercritical CO2 method produced better oil quality with higher antioxidant activity and polyphenols and tocopherols contents
