Polyunsaturated fatty acids from several plant species of the family Boraginaceae
Lipids from seeds of the plants Cynoglossum officinale (1), Echium vulgare (2), and Lappula squarrosa (3) of the family Boraginaceae growing in the Republic of Bashkortostan were studied. Four polyunsaturated acids, linoleic (LA), γ-linolenic (GLA), α-linolenic (ALA), and stearidonic (SA), were identified among the fatty acids. The principal acids of the neutral lipids (NL) were 18:1 and 18:2 in 1, ALA in 2 and 3, and GLA in approximately equal amounts in all three samples. The highest amount of SA (16.8 %) was found in 3. Unsaponified components of NL samples were identified by GC/MS. Alkaloids were observed in the pulp and polar lipids.
