Abstract

The composition of bran lipids from 3 cv. of rice is reported. Lipids extracted amounted to 21.9-23.0% of bran dry wt. and consisted of 88.1-89.2% neutral lipids, 6.3-7.0% glycolipids and 4.5-4.9% phospholipids. Neutral lipids were mostly triacylglycerols (83.0-85.5%), monoacylglycerols (5.9-6.8%) and small amounts of diacylglycerols, sterols and free fatty acids. 3 glycolipids and 8 phospholipids were separated and characterized. Acylated steryl glucoside and digalactosyldiacylglycerol were the main glycolipids, while monogalactosylmonoacylglycerol was present in small amounts. The major phospholipids were phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidic acid. Phosphatidylglycerol, lysophosphatidylcholine, lysophosphatidylethanolamine and acyl-phosphatidylethanolamine were present in small quantities.
