【 摘 要 】

Seeds, leaves and stems of six populations of twoEchiumspecies(Family Boraginaceae) from Iran were surveyed for the first time in a search for new sources of γ-linolenic acid (GLA, C18:3ω6), stearidonic acid (SDA, 18:4ω3) and other unsaturated fatty acids. Oils from the corresponding organs were analyzed bygas chromatography(GC) andgas chromatography-mass spectrometry (GC-MS)for total oil content and fatty acid composition. The range of total oil content varied between 0.7% in stems ofEchium amoenum, Behshahr population to 33.8% inseedsofE.amoenum,Ramsar population. The amounts of GLA ranged from 2.28% of total fatty acids inE. amoenumstems (Behshahr population) to 9.79% inEchium italicumseeds (Kaleybar population). In addition, considerable amounts of SDA were detected, with the highest values of 10.47 and 12.45% inseedsofE. italicumfrom Boumehen and Kaleybar populations, respectively. Other main unsaturated fatty acid components in the oils were α- linolenic acid (ALA, 18:3ω3) and linoleic acid (LA, C18:2ω6) with the highest amounts of 44.15 and 26.94% inE. amoenumseeds from Hezar Jarib and Behshahr populations, respectively. This data allows us to evaluate Iranian members ofEchiumgenus as alternative wild sources of valuable unsaturated fatty acids for commercial purposes.
