Abstract
The article is devoted to the study of lipids and fatty acid composition of the above-ground part of the Nepeta olgae Regel (L.) plant of the Laminaceae family. It was found that the content of neutral lipids (NL) is 5.54%, PL - 6.12%, and total lipids (NL, PL) - 11.66%. Of the neutral lipids, the unsaponifiable substances (HB) had a bright yellow color, which is explained by a small amount of carotenoids (88.87 mg%). Glycolipids dominate in PL. Among the unsaponifiable substances were found biologically active components such as hydrocarbons, carotenoids, aliphatic alcohols, sterols and triterpenols. Phytosterols were the main component of unsaponifiable NS. Quantitative and qualitative analysis of fatty acids from the plant Nepeta olgae Regel (L.) was carried out by gas chromatography (GC). 28 acids were identified, of which 11 compounds are saturated, and 7 compounds are unsaturated fatty acids. Of the fatty acids, the main ones are linolenic 18:3 (35.48), palmitic 16:0 (33.38%), as well as ?-3 polyunsaturated fatty acids, including eicosanoic 20:1, cis-11,14-eicosadienoic 20:2, 8,11,14-eicosatriene 20:3 + arachidonic 20:4. Extracts of Nepeta olgae Regel (L.) were distinguished by a high content of polyunsaturated acids, which determines their potential biological activity.
