    Fatty acid compositions of linseed (linum usitatissimum l.) genotypes of different origin cultivated in Turkey
    (Taylor & Francis Ltd, 2010) Bayrak, A.; Kıralan, Mustafa; İpek, A.; Arslan, N.; Şenkal, Belgin Coşge; Khawar, K. M.
    The study assessed the levels of variation in oil content and fatty acid composition among the linseed cultivars, lines and populations of different origins grown in Turkey The oil content ranged from 23.28 to 40.36% in the experimental materials. Three saturated (C-16:0, C-18:0 and C-20:0) and four unsaturated (C-18:1, C-18:2, C-18:3 and C-20:1) fatty acids, identified by GC represented 10.02% and 89.91% of the total oil, respectively The C-18:3 acid content ranged 48.08% to 57.58%. The contents of the C-18:1, C-18:2, C-16:0, and C-18:0 acids were 15.81 to 27.99, 11.18 to 16.13, 4.07 to 7.02 and 3.21 to 6.70%, respectively The C-20:0 and C-20:1 acids were minor fatty acids in these materials and ranged 0.11 to 0.24 and 0.10 to 0.24%, respectively

    Short communication. Variability of fatty acid and mineral content in linseed (Linum usitatissimum) lines from a range of European sources
    (Spanish Natl Inst Agricultural & Food Research & Technolo, 2010) Kıralan, Mustafa; Gökpınar, Fikri; İpek, Aydın; Bayrak, A.; Arslan, N.; Kök, Mehmet Şamil
    Linseed (Linnum usitatissimum) has recently gained popularity as a health food product. It has high levels of fatty acids and minerals, giving it characteristics beneficial for functional foods. This research is a comparative analysis of the fatty acid and mineral content of 23 European linseed lines. The levels of seven fatty acids were analysed using an Agilent 6890 N GC. Alfa-linolenic acid (ALA) (C18:3, n-3) was the most predominant, ranging from 49.4 to 56.4%, followed by oleic (C18:1, n-9; 19.8 to 28.8%), linoleic (C18:2, n-6; 10.8 to 16.0%), palmitic (C16:0, 4.1 to 6.2%) and stearic (C18:0, 3.3 to 7.1%) acids. In contrast arachidonic (C20:0) and gadoleic (C20:1) acids were only found at trace levels. One-way ANOVA test showed significant differences between the lines in terms of saturated and unsaturated fatty acid content (p < 0.05). A negative correlation (r = -0.74) exists between levels of ALA and oleic acid. The levels of ten minerals (Ca, Mg, Na, K, P, Cu, Fe, Mn, Zn and B) were also determined and showed significant variability between lines. The results can be used to assist variety selection in targeted breeding programs.
