摘　　要：本研究通过脂质组学方法研究油用亚麻籽的脂质组分,并进一步对不饱和脂肪酸进行初步分析。从油用亚麻籽中共获得46类2 309种脂质成分,并分析每个材料的脂质组成及含量,发现西藏种植油用亚麻能改变其脂质亚类的含量和占比;还从相关性角度分析了碳链长度为18、不饱和度为3的脂肪酸与其他脂质的相关性,初步从合成与代谢角度揭示了他们之间的关系;还发现西藏地区种植油用亚麻后,亚麻籽中的油酸、亚油酸、亚麻酸等不饱和脂肪酸含量呈上升趋势,为西藏地区引种油用亚麻及延长产业链、提高附加值等产业发展提供参考。The lipid composition of oilseed flax was analyzed based on lipidomics in this study,and unsaturated fatty acid were further analyzed.The total of 46 types of 2309 lipid components were obtained from seeds of oilseed flax.The lipid composition and content of each material were analyzed.The results showed that the content and proportion of lipid subclasses of oilseed flax in plateau cultivation could be changed.The correlation between fatty acids,carbon chain length of 18 and unsaturation of 3,and other lipids was also analyzed from the perspective of correlation,and their relationship was initially revealed from the perspective of synthesis and metabolism.The contents of unsaturated fatty acids such as oleic acid,linoleic acid and linolenic acid in flax seed were found to be on the rise after flax seed was planted in Tibet Region.The results could provide references for the development of oilseed flax introduction,extension of industry chain,and increase of added value in Tibet Region.
