The crude oil contents, total phenolic contents, volatile components and antioxidant activities of Onopordum anatolicum and Onopordum heteracanthum species seeds were investigated. In addition, the fatty acid profile, tocopherol contents, peroxide values, free fatty acidity and color values of the oils obtained from species seeds were determined. The oil contents of O. anatolicum and O. heteracanthum species seeds were found to be 15.84% and 12.54%, respectively. Total phenolic contents were found as 18554 and 13015 mg-GAE kg-1. DPPH (% inhibition) values in the studied seeds and BHT were determined as 84.41, 66.73, and 86.92% and ABTS values were determined as 121.18, 46.90, and 123.78 mmol Trolox eq. g-1. Linoleic acid (49.38 and 38.09%) and oleic acid (30.04 and 22.07%) were the most abundant fatty acids in the oil from seeds. In addition, a significant amount of α-tocopherol (1066.99 mg kg-1) was detected in O. anatolicum seed oil. Furthermore, 17 volatile compounds were detected in different amounts of each in the seeds of the species. In the light of all these findings, it was concluded that the seeds of O. anatolicum and O. heteracanthum could be appreciated as alternative oil raw materials, and used as natural antioxidant and polyunsaturated fatty acids sources in the formulation in functional foods.
