Özet
The fatty acid, tocopherol and sterol contents of the oils of several poppy seeds were investigated. The main fatty acids in poppy seed oils were linoleic (687.6-739.2 g kg-1), oleic (141.3-192.8 g kg-1) and palmitic (76.8-92.8 g kg-1). The oils contained an appreciable amount of γ-tocopherol (195.37-280.85 mg kg-1), with a mean value of 261.31 mg kg-1 and α-tocopherol (21.99-45.83 mg kg -1), with a mean value of 33.03 mg kg-1. The concentrations of total sterol ranged from 1099.84 mg kg-1 (K.pembe) to 4816.10 mg kg-1 (2. sinif beyaz), with a mean value of 2916.20 mg kg-1. The major sterols were β-sitosterol, ranging from 663.91 to 3244.39 mg kg-1; campesterol, ranging from 228.59 to 736.50 mg kg-1; and Δ5-avenasterol, ranging from 103.90 to 425.02 mg kg-1. The studied varieties of poppy seeds from Turkey were found to be a potential source of valuable oil.
