This study investigated the physiochemical characteristics of Xanthoceras sorbifolia seed oil. Xanthoceras sorbifolia seed oil was extracted by supercritical fluid extraction (420 atm, 50oC), hexane extraction and heat- pressed extraction (160oC, 180oC). Acid values and peroxide values were evaluated, as well as the degree of lipid oxidation. The heat-pressed (160oC) extraction gave a 53.5±2.5% higher yield of oil, compared with the other extraction methods. The acid values from the super critical fluid extraction were the highest, while peroxide values were highest from the heat-pressed extraction at 160oC (3.10 meq/kg). The contents of linolenic acid and oleic acid were 38.63～41.13% and 26.29～26.85%, respectively. Contents of stigmasterol and β-sitosterol were 6.01～6.49 mg/100 g and 58.19～59.85 mg/100 g, respectively. These results indicate that Xanthoceras sorbifolia seed oil can possibly serve as new edible oils.
