三种洋葱籽脂肪酸成分的对比研究_王强 . Comparative Analysis of Fatty Acids of Three Allium cepa L.Seeds by GC/MS

Abstract

The fatty acids from seeds oil of the Allium cepa L.were extracted by Soxhlet extraction.After esterification,GC/MS were used to analyze their components.23 components of fatty acid were identified from three kinds of onion seeds oil.The contents of the main fatty acids were linoleic acid,oleic acid and palmitic acid.And the content of unsaturated fatty acids was 81.35%(white),82.8%(red) and 78.94%(yellow).The results indicated that seeds oil of Allium cepa L.riched in unsaturated fatty acids,and the linoleic acid content is abundant.And it has wide application prospets to develop and utilize Allium cepa L.seeds as functional seasoning for both food and medicine.
