Hosta is a perennial ornamental plant used in Eastern folk medicine for the treatment of inflammatory diseases of the upper respiratory tract in particular coughs and pharyngolaryngeal, folliculitis, mastitis, urethritis, bruises and dysmenorrhea. The aim of the research was the study of the qualitative composition and quantitative content of fatty acids in rhizomes with roots, leaves, and flowers of Hosta lancifolia. Materials and methods. The fatty acid composition of the rhizomes with roots, leaves and flowers of Hosta lancifolia was studied by gas chromatography, which is based on the formation of methyl esters of fatty acids and their subsequent determination. The results of the study and their discussion. As the result of the study 16 fatty acids, 13 which of them were identified were collectively determined in all types of plant raw material. Unsaturated fatty acids quantitatively dominated in all types of plant raw material. Their total content in the rhizomes with roots were 73.82 %, in the leaves, - 64.9%, and in the flowers of Hosta lancifolia their content was 69.15 %. In Hosta lancifolia rhizomes with roots, leaves, and flowers linoleic and palmitic fatty acids were accumulated in significant amount. In addition, there was observed a high content of oleic acid – 20.63 % in rhizomes and roots. Linolenic acid mainly accumulated in flowers – 38.78 %. Oleic and arachidonic acids were detected in leaves at the significant amount. Their contents were almost identical and consistent with 15.15 % and 15.83 %. Eicosanic, begenic and lignocerinic fatty acids in all the investigated plant raw materials waere accumulated in small amount and their content was less than 1.00 %. Conclusion. Hosta lancifolia contains a considerable number of unsaturated fatty acids in rhizomes with roots, leaves, and flowers. The dominant acids in all the investigated raw materials were palmitic and linoleic acids, and the content of eicosanic, begenic and lignocerinic fatty acids was less than 1.00 % Author Biographies Вікторія Василівна Процька, National University of Pharmacy Pushkinska str., 53, Kharkiv, Ukraine, 61002 Department of Chemistry of Natural Compounds
