Abstract


The content of glyceride oil, phospholipid, sterol and tocopherol composition of 7 species of fam. Lamiaceae seeds were investigated. 8.7-28.6 % of glyceride oil in the seeds were determined. The content of phospholipids in the oils was found to be 1.0-1.6 %. Phosphatidylcholine (35.5-63.1 %), phosphatidylinositol (19.1-30.2 %) and phosphatidyl ethanolamine (5.8-21.6 %) were the main components in the phospholipid fraction. In the sterol fraction (0.1-0.3 % total sterols in the oils) 64.8-86.3 % are in free form and 13.7-35.2 % as sterol esters. β -Sitosterol predominates in all glyceride oils (48.8-87.9 %), followed by campesterol (1.5-22.5 %) and stigmasterol (1.1-12.8 %). 6.3-649.7 mg/kg tocopherols were found, mainly α -tocopherol (48.5-99.9%).
