Abstract
ZLATANOV, M., M. ANGELOVA and G. ANTOVA, 2007. Lipid composition of tobacco seeds. Bulg. J. Agric. Sci., 13: 539-544 The content and composition of lipids isolated from seeds of 7 Bulgarian tobacco species was investigated. 382-492g.kg -1 glyceride oil in the seed was founded to be. The biological active substances - fatty acids, phospholipids, sterols and tocopherols were studied. Palmitic (126367g.kg -1 ), oleic (152-263g.kg -1 ) and linoleic acid (176-627g.kg -1 ) predominated in the oils. The content of phospholipids, sterols and tocopherols in the oils was 2-15g.kg -1 , 3-8g.kg -1 and 2-195 mg/kg respectively. Phosphatidylcholine (247-405g.kg -1 ), phosphatidylinositol (215-276g.kg -1 ) and phosphatidylethanolamine (143-320g.kg -1 ) were found to be the main constituents. b-sitosterol (433-682g.kg -1 ), stigmasterol (102-188g.kg -1 ) and kampesterol (93-149g.kg -1 ) predominated in the sterol fraction. All of tocopherol derivatives were identified in the tocopherol fraction.
