楝叶吴茱萸和臭辣树种子油中十八碳链不饱和脂肪酸成分的分析鉴定

SEPARATION AND IDENTIFICATION OF C_(18) UNSATURATED FATTY ACIDS IN THE SEED OILS OF EUODIA MELIAEFOLIA BEMTH AND E. FARGESII DODE

摘要:

用＂远端羧基的化学修饰＂、色谱－质谱方法分离鉴定了楝叶吴茱萸和臭辣树种子油中的十八碳不饱和脂肪酸，含常见的亚油酸和不常见的１０－十八碳烯酸，以及在植物中首次发现的９，１３，１５－十八碳三烯酸．楝叶吴株萸和臭辣树种子油的脂肪酸组成（％）分别为：棕榈酸１０．１，１０．７；硬脂酸１．０，１．９；棕榈油酸２１．２，２０．７；１０－十八碳烯酸２８．５，３１．７；亚油酸２４．２，１７．５；９，１３，１５－十八碳三烯酸１５．０，１４．９．

Abstract:

The C18 unsaturated fatty acids in the seed oils of Euodia meliaefolia and E.fargesii were separated and identified by means of remote functional group modificationmethod and GC/MS. An usual linoleic acid, unusual 10-octadecenoic acid and a newconjugated acid as 9, 13, 15-octadecatrienoic acid were found. The composition of fattyacids in seed oils of E. meliaefolia and E. fargesii were palmitic 10.1%, 10.7%; stearic1.0%, 1.9%; palmitoleic 21.2%, 20.7%; 10-octadecenoic 28.5%, 31.7%; linoleic 24.2%,17.5% and 9, 13, 15-octadecatrienoic 15.0%, 14.9%, respectively.
