COMPARATIVE ANALYSIS OF THE NONPOLAR FRACTION OF THE AERIAL AND UNDERGROUND PARTS OF THE LIMONIUM GMELINII PLANTS BY THE GC-MS METHOD

Аннотация

This article discusses the chemical composition of the non-polar fraction obtained from the aerial and
underground parts of Limonium gmelinii (Willd.) harvested in the Almaty region in 2018. Extracts were obtained by
the method of solvent extraction with hexane and studied by means of chromato-mass spectrometry on a gas
chromatograph with a mass-selective detector.
As a result, 22 compounds were isolated from the aerial part of Limonium gmelinii plant, out of which
dominating both quantitatively and qualitatively are hydrocarbons, such as genicosane and eicosane and tricosane;
quinoline and phytol derivatives were isolated as well. High content of phytol acetate related to derivatives of acyclic
diterpene alcohols has been revealed. In addition, the higher alcohol 3,7,11,15-tetramethyl-2-hexadecan-1-ol has
been identified.
Analysis of the non-polar extract obtained from the roots of Limonium gmelinii allowed us to isolate 14
compounds, out of which the major share in the amount belongs to the esters of higher carboxylic acids and
hydrocarbons. Esters are represented as ethyl esters of hexadecanoic, oleic and linoleic acids with prevalence of
polyene acids in them. Among the hydrocarbons, tridecane, tetradecane, heptadecane, octadecane and tetracosane are
the most abundant.
