大麦籽粒油脂肪酸成分分析_郑敏燕 . Analysis of Fatty Components from the Seed of Barley

Abstract

The amount of fatty and the compositions of fatty acids in the seeds of barley were determined and analyzed. Rude fatty acids from the seeds of barley were extracted by Soxhler extractor and the acid-hydrolysis method. After being methyl-esterified with the presence of KOH/MeOH,the components of fatty acids were analyzed by GC/MS. The results show that the extracting amounts of rude fatty acids using these two methods are 1.87g/100g and 1.98g/100g,respectively. 12 and 14 kinds of fatty acids were obtained from the two methods. The main components are linoleic acid(52.20%,53.27%) ,palmitic acid(22.75%,22.15%) ,oleic acid(16.35%,14.63%) ,and linolenic acid(4.65%,5.48%) . Most of the fatty acids are polyunsaturated fatty ones,which constitute more than 75% of the total mass. The results could offer some basic data to the food research related with barley.
