COMPARATIVE ANALYSIS OF THE FATTY ACID COMPOSITION OF OIL EXTRACT OF JUNIPERUS COMMUNIS L. AND JUNIPERUS SERAVSCHANICA K. BY GAS-LIQUID CHROMATOGRAPHY METHOD

The article presents the results of a comparative analysis of the composition of fatty acids in oil extracts of common juniper (Juniperus communis L.) and Zarafshan (Juniperus communis L.) fruits in cottonseed and sunflower oil. The analysis was carried out on an Agilent Technologies 6890 N gas chromatograph with a flame ionization detector. Oil extracts in cottonseed oil have been shown to be rich in palmitic acid, while sunflower oil extract contains more linolenic acid. The main physicochemical constants of oil extracts were determined. Oil extracts contain from 0.9 to 1.1% tannins determined by titration. HPLC determined the content of quercetin in the oil extract of common juniper (0.130%) and Zarafshan (0.200%) in cottonseed oil. Oil extracts of common juniper contain quercetin in sunflower oil 0.0142%, and juniper zarafshan 0.0122%. The obtained extracts have posersed interest for converting them into emulsions, liniments and other dispersed systems.
