The content and composition of lipids isolated from the seeds of seven Bulgarian tobacco varieties were investigated. Glyceride oil in the seed was found to be 30.1-41.3%. The biologically active substances - fatty acids, phospholipids, sterols and tocopherols were studied. Palmitic (16.4-27.7%), oleic (17.6-39.5%) and linoleic acids (5.2-51.9%) predominated in the oils. The content of phospholipids, sterols and tocopherols in the oils was 1.0-1.7%, 0.3-0.8% and 5-72 mg/kg, respectively. Phosphatidylcholine (35.2-41.8%), phosphatidylinositol (23.8-29.8%) and phosphatidylethanolamine (11.6-21.1%) were found to be the main components in the phospholipid fraction. Beta-sitosterol (59.4-65.9%), stigmasterol (10.4-13.9%) and kampesterol (9.6-14.8%) predominated in the sterol fraction. Gamma-tocopherol (76.5-96.6%) was the main component in the tocopherol fraction.
