Fatty acid profiles of the seed oils in two groups of Anchusa officinalis L.

Abstract

Total seed oil and fatty acid compositions of two informal groups of Anchusa officinalis L. were studied in orderto provide additional information for the delineation of the groups. Major fatty acids were linoleic (C18:2n6),oleic (C18:1n9), α-linolenic (C18:3n3), γ-linolenic (C18:3n6), palmitic (C16:0) and stearidonic acid (C18:4n3)respectively. The lower levels were observed in stearic (C18:0), eicosenoic (C20:1n9) and erucic acids(C22:1n9). Linoleic (24,4 to 25,8%) and oleic acids (23,2 to 25,5%) were detected in the highest levels. α- linolenic (14,5 to 15,1%) and γ-linolenic acid (12,5 to 12,6%) as an unusual fatty acid in plants were also at thehigh concentrations in both groups. Saturated fatty acids in total were observed at the lower levels generally (1,9- 8,9%). Significantly difference for the fatty acid profiles between the groups were found (p
