There was established the lipid composition of the seeds of Vitex agnus castus L. by the qualitative and quantitative methods of analyses. There were received neutral lipids from the seeds by extraction with hexane in the yield 10%, counted on dry material. For the divide of neutral lipids there was used silica gel plates LS 5/40 in the systems of solvents: 1. petroleum ether-diethylether-acidum aceticum (85:14:1), 2. hexane-diethylether (1:1). After obtaining neutral lipids from the residual plant shrot pollar lipids was extracted with the mixture of chloroform-methanol (2:1) and was divided on silica gel plates LS 5/40, mobile phase: 1. chloroform-methanol-25% ammonium hydrate 2. chloroform-methanol icy acetic acid-water (170:25:25:6). In the sum of polar lipids qualitatively were established phospholipids: lisophosphatidylcholine, phosphatidylinosit, phospatidylethanolamine and N-acylphosphatidylethanolamine, in neutral lipids, hydrocarbons, triglycerids, free fatty acids and sterines. By the method of high performance liquid chromatography analyses there were identified following free fatty acids: lauric, myristic, palmitic, stearic, linolic, linolenic, arachidic and begenic, unsaturated oleic and polyunsaturated linolic and linolenic acids. obtained oil with unique composition from the seeds of Vitex agnus-castus indicates to its high biological activity and importance for usage in medicine.
