Тип записи:Публикация, Study of the chemical composition of raw alcohol obtained from the tuber of dahlia(2022-06-15); ; ; ; The raw material for alcohol production is a variety of plant materials, which contain sufficient amounts of digestible sugars or other carbohydrates that can be saccharified. Dahlias are tuberous plants of the Asteraceae family with a quick and powerful growth and a long vegetation period. The study of the chemical composition of dahlia tubers is of undoubted interest in terms of practical health care. Dahlia tubers are the main raw material for obtaining inulin, which has a wide range of pharmacological action. The vegetative (aboveground) part of dahlia has been an object of research. The purpose of this study has been to study the chemical composition of raw alcohol, obtained from the dahlia tubers. For this purpose, the chemical composition of the tuber of dahlia plants belonging to the Compositae family has been studied. It has been found that the tubers of dahlia contain a large amount of biologically active substances: protein, coumarin, polyphenol, pectin and inulin. Dry alcoholic yeast (TC BY 100104781.010-2005 dried alcoholic yeast Saccharomyces cerevisiae produced in Belarus) has been used as yeast. The fermentation process has taken place at the room temperature for 2-3 weeks. After 2 weeks it has been filtered, the quantity of wort has been measured and distilled. The chemical composition of the raw alcohol, obtained from dahlia tubers has been identified on an Agilent 7890A/5975C chromato-mass spectrometer. - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, DETERMINATION OF HIGHER FATTY ACIDS IN THE COMPOSITION OF URTІCA DIОICA LEAVES(2023-12-15); ; ; 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.
