Abstract
The aim of this work was to study the lipid composition of the fruit of Corylus avellana L. (Betulaceae) and seeds of Persica vulgaris L. (Rosaceae). Using the method of high performance liquid chromatography (HPLC), seven saturated, one mono-unsaturated and two poly-unsaturated fatty acids were identified. It is remarkable that hexadecanoic, 9-octadecenoic acid and 9, 12-octadecadienoic acids are predominant in fatty oil. From the fruits of Corylus avellana neutral lipids with a yield of 61%, relative to the air-dry raw material were obtained. Five phospholipids and seven amino acids were identified from the polar lipids of Corylus avellana. Fatty oils from the seeds of Persica vulgaris (Rosaceae) were studied. HPLC analysis of the fatty oils show presence of five saturated, one unsaturated and two poly-unsaturated fatty acids. Among of them dominants are: 9-octadecenoic acid, 9, 12-octadecadienoic and 9,12,15-octadecatrienoic acid, which are not synthesized in the human body and are presented as an irreplaceable fatty acids. The characteristics of the fatty acid composition of the fatty oil of the seeds of Persica vulgaris is related to the climatic conditions of the eastern regions of Georgia and corresponds to the tendency of growth of unsaturation with changing environmental factors.
