DETERMINATION OF HIGHER FATTY ACIDS IN THE COMPOSITION OF URTІCA DIОICA LEAVES

Abstract

Urtіca diоica is a tall perennial plant with an unbranched stem and large simple serrated leaves. Urtіca is widespread in many parts of the globe. Including in North Africa, in some regions of Asia, Europe and North America. Urtіca contains many biologically active substances, such as flavonoids, carotenoids, phenolic compounds, vitamins and minerals, which have a beneficial effect on the human body. Due to its antioxidant, anti-inflammatory and antibacterial properties, it is used in medicine and cosmetology. Currently, urtica dioica is widely used by traditional medicines. The purpose of the study. Determination of the upper fatty acids contained in the leaves of dioecious nettle. The research method. A gas-liquid chromatograph "Crystallux-4000 M" with a mass spectrum detector of the PIT and MS 7-800 brands was used. The object of the study was a dioecious nettle, collected in 2021 from Mount Medeu, Almaty. The study showed that the leaves of the dioecious nettle contain 8 fatty acids. The most common in the leaves of urtica dioica are methyl butyrate, methyl hexanoate. The conclusion of the study. High fatty acids in the composition of dicotyledonous nettle leaves were detected in a gas-liquid chromatograph "Kristallux-4000 M" with a mass spectrum detector of the PID brand and "MS7-800". As a result, 8 fatty acids with a high content were found in the dioecious nettle leaf. Of these, methylbutyrate and methylhexanoate are found in the largest amounts.
