The content and composition of lipids isolated from seeds of 7 Bulgarian tobacco species was investigated. glyceride oil in the seed was founded to be. The biological active substances - fatty acids, phospholipids, sterols and tocopherols were studied. Palmitic (, oleic ( and linoleic acid ( predominated in the oils. The content of phospholipids, sterols and tocopherols in the oils was, and 2-195 mg/kg respectively. Phosphatidylcholine (, phosphatidylinositol ( and phosphatidylethanolamine ( were found to be the main constituents. b-sitosterol (, stigmasterol ( and kampesterol ( predominated in the sterol fraction. All of tocopherol derivatives were identified in the tocopherol fraction.
