In this study, bioactive lipid components such as fatty acid composition, tocopherol and total phenolics content and antioxidant activity of few wild plant seed extracts were determined. The oil contents of seed samples changed between 3.75 g/100 g (Onobrychis viciifolia Scop) and 17.94 g/100 g (Pimpinella saxifrage L.). While oleic acid contents of seed oils change between 10.4% (Trifolium repens) and 29.5% (Onobrychis viciifolia Scop), linoleic acid contents of oil samples varied from 16.3% (Onobrychis viciifolia Scop) and 64.2% (Trifolium repens) (p < 0.05). While α-tocopherol contents of oil samples change between 2.112 (Pimpinella saxifrage L.) and 228.279 mg/100 g (Trifolium pratense), ɣ-tocopherol contents ranged from 0.466 (Phleum pratense) to 67.128 mg/100 g (Onobrychis viciifolia Scop). Also, α-tocotrienol contents of Onobrychis viciifolia Scop and Phleum pratense were 30.815 and 23.787 mg/100 g, respectively. Results showed some differences in total phenol contents and antioxidant activity values of extracts depending on plant species. The present study indicates that this seed oils are rich in fatty acid and tocopherol.
