Trigonella caerulea (L.) Ser. is an annual plant of the Trigonella genus in the Leguminosae family. The
dried powdered leaves and flowers are used as a spice in soups and potato dishes. This herb is
also used in cheese making. The purpose of this work is the analysis of the fatty acid composition
of seed oil of Trigonella caerulea (L.) Ser. which have been cultivated in the Republic of Belarus. Oil
was extracted with boiling hexane in the Soxhlet extractor for 10 hours, and then hexane was
deleted. For GC analysis the derivatisation of the samples of oil for generation of methyl ethers
of fatty acids was spent. The chromatograph Crystal 5000.1 with a quartz capillary column 60 m
long was used. The oil of Trigonella caerulea (L.) Ser. content was 5.16%. It has been established,
that oil was mainly composed of linoleic (42.27%), α-linolenic (23.91%), рalmitic (12.05%), оleic
(10.95%), stearic acids (1.95%). Trigonella caerulea (L.) Ser. oil was rich unsaturated fatty acids
(nearly 78% of the total fatty acids), and polyunsaturated fatty acids accounted for 66.3% (mass
percentage) of the total amount. Oil of Trigonella caerulea (L.) Ser. can be added in cosmetic
products as natural analogue of vitamin F.
