Identification and quantitative determination of the lipids of dried Origanum dictamnus leaves

The Origanum dictamnus plant was examined for its lipid and fatty acid compositions. A combination of chromatographic techniques has been employed for the qualitative and quantitative determination of the lipids of dried leaves of O. dictamnus. The following polar lipids were identified: mono-, di- and poly-digalactosyl diglycerides, sulpholipids, cerebrosides, phosphatidyl-ethanolamine, phosphatidylserine, phosphatidylglycerol, phosphatidylinositol, phosphatidyl choline and phosphatidic acid. The non-polar lipids identified were sterols, steryl esters, fatty alcohols, free fatty acid, waxes, traces of triglyceride, triterpenic acids and essential oil. The predominant fatty acids were palmitic, oleic and linoleic acids.
