The compositions of fatty acids, tocopherols, polyphenols, sterols, and the total phenol contents of cold pressed oils obtained from five varieties of safflower seeds and ten varieties of camelina seeds cultivated in Turkey were determined. Total phenol contents of safflower oils were higher (272.20-525.30mg GAE/kg) than camelina seed oils (25.90-63.70mg GAE/kg). Apigenin, luteolin, tyrosol, syringic acid, 3-hydroxytyrosol, p-coumaric acid and sinapic acid were detected in seed oils. Camelina seed oils were rich in tocopherol (144.11-168.69mg/100g). -Tocopherol was the predominant tocopherol in camelina seed oils consisting of averagely 80% of total tocopherol, while -tocopherol was the main compound of safflower seed oils, representing 97.85-98.53% of total tocopherols. -Sitosterol was the major sterol in both type of seed oils. Its concentration ranged between 92.51-121.83mg/100g and 80.52-25.54mg/100g in safflower seed and camelina oils, respectively. Camelina seed oils contained 22.31-26.57% linolenic acid, 21.25-24.05% linoleic acid and 19.46-21.47% oleic acid, whereas safflower seed oils mainly consisted of linoleic (28.03-76.85%) and oleic (13.01-62.61%) acids.
