gamma-Linolenic acid content and fatty acid composition of Boraginaceae seed oils

摘要

Eleven species of the Boraginaceae family collected in Turkey were analyzed with respect to the amount of gamma-linolenic acid as well as fatty acid composition.gamma-Linolenic acid was found in all species,except for Heliotropium lasiocarpum Fisch.& Mey.and Heliotropium dolosum De Not.Seed oil content ranged from 1.5% in H.lasiocarpum to 22.0% in Anchusa leptophylla ssp.leptophylla.The content of gamma-linolenic acid ranged from 1.7% of total fatty acids in Paracaryum racemosum (Schreber)Britten var.race-mosum to 13.7% in A.leptophylla Roemer & Shultes ssp.leptophylla.According to data from our study,A.leptophylla ssp.leptophylla (13.7%),Anchusa azurea Miller var.azurea (11.9%)and Echium plantagineum L.(12.2%)might be considered as new sources of gamma-linolenic acid.
