Considering diverse applications of oils, there is increasing interest in identifying and exploring potential new oilseed crops. One such promising crop is Thlaspi alliaceum L. (garlic pennycress) from the Brassicaceae family. The present paper deals with the yield, physicochemical properties, and fatty acid composition of garlic pennycress seed oil (GPSO) obtained by maceration (70°C, n-hexane:seed ratio 10:1 mL/g, 10 min), Soxhlet extraction (n-hexane:seed ratio 10:1 mL/g, 6 h), and cold pressing (8 mm nozzles) of the seeds. The highest GPSO yield was achieved by Soxhlet extraction (18.43±0.21 g/100g), followed by cold pressing (13.23±0.56 g/100g) and maceration (13.09±0.08 g/100g). The physicochemical properties of the obtained GPSOs were not influenced by the extraction technique. All obtained GPSOs are characterized by low iodine, peroxide, and acid values, refractive indexes, and high viscosities. The most abundant fatty acids in the oils are oleic and linoleic acid with similar content in all GPSOs (30-32%), followed by behenic acid (13.6- 15.5%). The oils rich in behenic acid are valuable feedstocks for the food, pharmaceutical, and cosmetic industries. The significant content of behenic acid in GPSO indicates its high potential for broad applications.
