Effects of growth conditions on fatty acids and tocopherols in Camelina sativa oil
2002
Zubr, J. | Matthaus, B.
Oil samples obtained from the seed of Camelina sativa (L.) Crantz were analysed for the content of fatty acids and tocopherols. The evaluation of the results in this report includes three promising cultivars from a collection of seven summer cultivars and varieties grown in field trials 1997 at five remote localities representing Central Europe, Northern Europe and Scandinavia (7-17 degrees E, 48-60 degrees N). At all experimental sites identical cultivation practices with small modifications were used. The analyses reconfirmed the known specific profile of fatty acids in camelina oil. The average content of oleic acid (18:1n-9) was 14.87 +/- 0.17%, linoleic acid (18:2n-6) 15.23 +/- 0.17%, alpha-linolenic acid (18:3n-3) 36.82 +/- 0.27%, gondoic acid (20:1n-9) 15.48 +/- 0.16% and of erucic acid (22:1n-9) 2.83 +/- 0.07%. The analyses for tocopherols (T) revealed the average content of alpha-T at 28.07 +/- 2.58 ppm, gamma-T 742 +/- 14.80 ppm, delta-T 20.47 +/- 0.92 ppm and of plastochromanol (P-8) 14.94 +/- 1.05 ppm. Neither beta-T nor tocotrienols were detectable. The average content of total tocopherols was 806 +/- 15.70 ppm. Both the analyses for fatty acids and for tocopherols disclosed considerable qualitative differences between the oil samples. The variation was ascribed to the combined effects of climatic and soil conditions under which the crop was grown.
