Neutral lipids of barley grain

Abstract

Fractionation of the neutral lipids of the grain of barley cv. Kearney (winter type) and Prilar (spring type) by thin-layer chromatography produced 11 individual lipid classes. Gravimetric determination of each fraction showed the triglycerides to be the predominant class. Somewhat smaller amounts of 1,2-diglycerides, 1,3-diglycerides, free sterols, free fatty acids, sterol esters, hydrocarbons, and small amounts of 4 unknowns were present. Fatty acids present in the fractions ranged from lauric (C12:0) to arachidic (C20:0). Linoleic acid (C18:2) was the principal fatty acid in all the saponifiable fractions, excluding sterols, except unknown no. 4 in which oleic acid (C18:1) was predominant.
