Characterization of fatty acids in some plants growing in Georgia

Abstract

The objective of the study was to evaluate of the fatty acids' composition in the oils from the seeds of Vitex rotundifolia and the roots of Cichorium intybus by GC-MS. Oils used for analysis have been obtained by extraction using the n-hexane in the room temperature. The oils were esterified to bring them into a vaporous phase, transforming the fatty acid from oil into fatty acids methyl esters. Major components of V. rotundifolia seed oil was linoleic acid (36,9%), followed by palmitic acid (15.2%), oleic acid (13.3%) and the major components of C. intybus root oil was palmitic acid (55,9%), linoleic acid (11,8%), followed by, oleic acid (10,2%). It can be concluded that V. rotundifolia seeds and C. intybus root oils are an excellent source of essential fatty acids omega-6 and omega-9. In the sum of polar lipids were determined existences of following phospholipids: phosphatidylcholine, phosphatidylethanolamine, N-acyllysophosphatidylethanolamine, N-acylphosphatidylethanolamine, lysophosphatidylinositol, phosphatidylinositol.
