Nutrients in grass seeds: I. Fatty acids in grass seed lipids

Abstract

The fatty acid composition was investigated in samples of 7 different grass seeds. The analyses were carried out by gas-liquid chromatography of the methyl esters of the fatty acids before and after hydrogenation. Six samples had fat contents ranging from 0.8 to 2.3%. Their lipids had linoleic acid contents from 44.9 to 67.1%, oleic acid from 13.6 to 22.0% and palmitic acid from 10.6 to 14.9%. Linolenic acid ranged from 4.5 to 8.5%. Values for 9 minor fatty acids are also reported. One sample, cocksfoot grass seed, showed a higher fat content, 6.3%. The fatty acid pattern also differed, showing the values: linoleic acid 38.9%, oleic acid 42.5%, palmitic acid 12.2%, and linolenic acid 2.6%. || ABSTRACT AUTHORS: Authors
