Composition of the Young Green Barley and Wheat Leaves

Abstract

Composition of young green leaves of barley and wheat were analyzed for volatile compounds by GC/MS. The volatile compounds identified in the barley extract were eight aliphatic alcohols; 18 aliphatic aldehydes; 17 aliphatic ketones; two aliphatic esters; one aliphatic acid; 20 heterocyclic compounds (furans, pyrroles, thiazoles, and pyrazines); 15 terpenes and related compounds; 12 aromatic compounds; and one sulfur containing compound. The main components of barley extract were (E)-β-ionone (4.55 ppm), benzaldehyde (2.98 ppm), furfural (2.40 ppm), 5,6-epoxy-β-ionone (2.36 ppm), and benzylaldehyde (2.32 ppm). Volatile compounds found in the wheat extract were similar to those found in the barley extract. The volatile compounds identified in the wheat extract were 11 aliphatic alcohols; 20 aliphatic aldehydes; 16 aliphatic ketones; four aliphatic esters; five aliphatic acids; 10 heterocyclic compounds (furans, pyrroles, and pyrazines); 18 terpenes and related compounds; 14 aromatic compounds; five nitriles; and two sulfur containing compounds. The main components of wheat extract were 5-hexenenitrile (5.51 ppm), phytol (4.62 ppm), phenyl acetonitrile (4.39 ppm), 4-pentennitrile (4.36 ppm), (E)-β-ionone (3.40 ppm), 5,6-epoxy-β-ionone (2.21 ppm), and β-cyclocitral (1.83 ppm).
