Composition of biologically active lipids of <i>lamiaceae</i> seed oils

By G. A. Antova and M. D. Zlatanov


The content of glyceride oil, phospholipid, sterol and tocopherol composition of 7 species of fam. <i>Lamiaceae</i> 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. &#206;&#178; -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 &#206;&#177; -tocopherol (48.5-99.9%).<br><br>Se estudia el contenido en aceite, fosfol&#237;pidos, esteroles y tocoferol de semillas pertenecientes a 7 especies de la Familia <i>Lamiaceae</i>. Se encontraron valores comprendidos entre 8.7-28.6 % para los aceites en las semillas. El contenido en fosfol&#237;pidos para los aceites fue del 1.0-1.6 %. Los principales componentes de la fracci&#243;n fosfol&#237;pido fueron: fosfatidilcolina (35.5-63.1 %), fosfatidilinositol (19.1-30.2 %) y fosfatidiletanolamina (5.8-21.6 %). En la fracci&#243;n de esteroles (0.1-0.3 % de esteroles totales en las muestras de aceites), 64.8-86.3 % estaban presentes en forma libre y 13.7-35.2 % como esteres de esteroles. El &#206;&#178; -Sitosterol es el que predomina (48.8-87.9 %), seguido de campesterol (1.5-22.5 %) y stigmasterol (1.1-12.8 %). Se encontr&#243; un contenido en tocoferoles de 6.3-649.7 mg/kg, principalmente &#206;&#177; -tocopherol (48.5-99.9 %)
