Polar lipids of the total lipid extracted from 4 representative varieties of barley grown in Korea and their corresponding malt were studied. The average content of glycolipids and phospholipids in barley were 8.9 and 17.3% and their average content of malt were 12.3 and 19.2%, respectively. Among the glycoliplds of the barley, digalactosyl diglycerides and monogalactosyl diglycerides were the major components, and the malts showed somewhat lower amounts of those components. Steryl glycosides and cerebrosides were the minor components of the glycolipids, and malts of the barley showed somewhat increased amounts of those components. Phosphatidyl cholines, lysophosphatidyl cholines, diphosphatidyl glycerols, and phosphatidyl ethanolamines were the major components of the phospholipids for the barley and represented 85 to 90% of the total phospholipids. The malts had lower amounts of phosphatidyl cholines and the lyso analog, and higher amounts of phosphatidyl ethnolamines and diphosphatidyl glycerols. The fatty acid composition in the glycolipids and phospholipids were similar to the pattern in those of the neutral lipids. But glycolipids and phospholipids fractions contained a higher percent of linoleic and palmitic acid than other lipid fractions, respectively.
