Creeping mustard (Acroptilon repens) is a perennial plant of the Asteraceae family and is one of the most persistent and difficult to eradicate weeds. They are actively fighting it, but the methods of combating it are very complex, high-cost and ineffective. Creeping mustard is used in folk medicine to treat many diseases, but the phytochemical composition of this plant has not been sufficiently studied. The purpose of this work: to study the chemical composition of this plant. This research will help find new sources of biologically active substances (BAS), as well as solve the problem of clogging of agricultural land. Methodology: generally accepted methods for determining the main biologically active substances in plant materials, spectrophotometry, high-performance liquid chromatography (HPLC).Results: the phytochemical analysis of the composition of Acroptilon repens collected in the Almaty region was carried out. The results showed the following characteristics: moisture (11.4%), ash content (6.21%), extractives (22.5%), organic acids (1.9%), flavonoids (3.75%), tannins (0.6%), alkaloids (1.86%), coumarins (1.18%), saponins (2.47%), carbohydrates (2.5%). By multi-element atomic emission analysis, 8 elements were identified in plant ash, with Mg (77.09 μg/ml), K (77.28 μg/ml), Na (34.075 μg/ml) and Ca (28.07 μg/ml) predominant in plant ash. Significant quantities of these elements indicate the high physiological activity of creeping bitterweed. Additionally, a total alcohol extract was obtained (96% ethyl alcohol was used), which was further divided into fractions using petroleum ether, hexane, ethyl acetate and butanol. The ethyl acetate fraction was analyzed using HPLC. The results of the study showed the presence of naringin in the ethyl acetate extract. Conclusion: The results obtained provide important information about the chemical composition of the studied plant Acroptilon repens, which contains a complex of biologically active substances, which may be useful for further scientific and applied research.
