Abstract
The article presents the results of a study of the nominal part of the Salicornia europaea L. population growing in the Republic of Abai. An elemental analysis of plant raw materials was carried out, the content of total carbon, organic carbon, nitrogen and sulfur was determined. An alcoholic extract of vegetable raw materials was obtained in the Soxlet apparatus. The extract was filtered and used for chemical analysis. Qualitative reactions revealed the presence of a number of biologically active substances in the extract, such as proteins, terpenes and steroids, tannins, xanthones, phenolic compounds, flavonoids, carboxylic acids and caratinoids. The quantitative determination of flavonoids and catechins in the extract was carried out. The spectrophotometry method showed that the content of flavonoids in the plant extract in terms of quercetin is 0.31±0.03 µg/ml. The content of catechins in the extract was determined by liquid chromatography, which amounted to 34.01±3.40 µg/ml. The FRAP (Iron Reducing Antioxidant Power) method is used an antioxidant strategy. It has been shown that with an increase in the concentration of the extract from 0.01 to 0.05 mg/ml, the antioxidant activity increases. At an extract concentration of 0.05 mg/ml, the antioxidant activity is 3.084 mg AAE/ml of the extract. It is concluded that the plant can serve as a raw material for production of cosmeceutical products.
