Polyunsaturated fatty acids of <Emphasis Type="Italic">Cortusa turkestanica</Emphasis> seed oil

The composition of free and bound lipids from seeds of Cortusa turkestanica A. Lozinsk (Primulaceae) was studied. The fatty acid composition of principal acyl-containing classes was established using GC/MS. It was found that triacylglycerines isolated from free and bound lipids contained the usual acids and rarely encountered polyunsaturated 18:3 ω-6 (γ-linolenic, 8.8 and 3.2%) and 18:4 ω-3 (stearidonic, 0.7 and 0.4%) acids and were enriched in linoleic acid (18:2, ω-6, 58.2 and 60.8%, respectively). It was found that polyunsaturated 18:3 ω-6 and 18:4 ω-3 acids were missing in the free form and were found among polar substances of bound lipids.
