Abstract Introduction. With due consideration of the properties of fatty acids, as well as their importance for normal life activity and human development, research into the fatty acid composition of poorly studied plants and the search for new domestic plant sources of polyunsaturated fatty acids is a mainstream trend in modern pharmacy. Aim. Aim of research – determination of fatty acid qualitative composition and content in threshed grass, stalks, roots and seeds of Night-scented stock ‘Queen of Night’ and ‘Evening Scent’ cultivars as grown in Ukraine. Methods. Gas chromatography. Results. Both cultivars of Night-scented stock taken for analysis had similar fatty acid composition – 5 saturated, 5 (4 for seeds) monounsaturated and 2 polyunsaturated fatty acids, Quantitatively, in all tested parts of the herb polyunsaturated and monounsaturated fatty acid dominated, making in total 88.92% and 88.62% in the seeds of Queen of Night and Evening Scent cultivars, respectively, and averaging 65% in other parts of the tested cultivars. Linolenic and linoleic acids prevailed among the polyunsaturated fatty acids, whereas oleic acid prevailed among the monounsaturated. Conclusion. Night-scented stock can be utilized as a source of polyunsaturated fatty acids for the development of drugs and for standardization of tested raw materials.

Abstract A capillary gas chromatographic (CGC) method is described for the determination of cis,cis-methylene interrupted polyunsaturated fatty acids (cis-PUFA) in fats and oils. The sample is saponified and the liberated fatty acids are esterified to the corresponding methyl esters. The latter are analyzed by CGC using a 60M SP2340 capillary column. Area percent values for 9,12-cis,cis-C18:2 and 9,12,15-cis,cis,cis-C18:3 fatty acid methyl esters are summed to give the total cis-PUFA content. Gas chromatographic results agreed well with those obtained by an enzymatic lipoxygenase method at the 31-48% cis-PUFA levels with a correlation coefficient of 0.98. The method has a precision (relative standard deviation) of 0.33% at a 44.4% cis-PUFA level in margarine oil.
