Fatty acid composition of night-scented stock (Matthiola bicornis (Sibth. & Sm.) DC.) raw materials

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.

Comparative analysis of the fatty acid composition of raw material of rye (Khamarka variety) and barley (Shedevr variety) of Ukrainian selection

“…After methylation the ampoules were opened, their content was transferred to a test tube with adding zinc sulfate powder on the tip of a scalpel, 2 ml of distilled water and 2 ml of hexane for methyl ethers' extraction. After thorough stirring and decantation, hexane extract was filtered and used for further chromatographic analysis [16,17].…”
