【摘要】 在杉木[Cunighamia lancelata (lamb.) Hook.]种子油中用尿素包合法和柱层析结合的方法分离出一种不常见的脂肪酸,经GC、UV、MS、NMR和IR分析证实该酸为顺-5,11,14,17二十碳四烯酸。本实验分析了4种杉科种子油脂肪酸的组成,发现它们都含有顺-5,11,14,17二十碳四烯酸,此发现在国内外未见报道。更多还原

【Abstract】 An unusual fatty acid was isolated from seed-oil of Cuninghamia lancelata (Lamb.) Hook. by the combined method of urea adducts formation and column chromatography. On the basis of data obtained from GC, UV, MS, NMR, and IR, this particular fatty acid was elucidated as cis-5, 11, 14, 17, Eicosatraenoic acid.更多还原
