Garden strawberries (Fragaria ananassa) are widely cultivated on the territory of Russia on industrial plantations and private garden plots to obtain the fruits (berries) of this plant and their use as a valuable food product. When harvesting fruits, other parts of the garden strawberry are not used, however, its vegetative parts are a source of biologically active substances (BAS) and are of interest for the pharmaceutical and cosmetic industries [1, 4]. The biological activity of garden strawberry leaf extracts is due to the presence of secondary metabolites of a phenolic nature; their content in raw materials reaches more than 3% in some samples [2, 3]. Considering that the main group of biologically active substances of this raw material are flavonoids, the Department of Pharmacognosy with a course of botany conducted research to develop a method for quantitative determination of the amount of flavonoids in terms of rutin. Spectrophotometry was chosen as the optimal method for assessing the content of this group of substances in medicinal plant raw materials - leaves of garden strawberries, which allows determining the amount of flavonoids in terms of the dominant compound and obtaining reliable and reproducible results of quantitative analysis [8, 11]. The technological properties were studied and a therapeutic dose of dry strawberry extract was proposed, optimal compositions were selected and technologies of sachet-granules with dry strawberry extract were developed. The method for the quantitative determination of flavonoids in terms of rutin was validated. The results of the study can be used in the future in the development of draft regulatory documents for sachet-granules with dry strawberry extract of garden leaves and the study of their pharmacological activity.

Introduction. Currently, close attention in the field of pharmacy and medicine is directed to the search for new sources of biologically active substances of various origins, including vegetable. The woody plant Elaeagnus argentea is considered as a promising source. Despite its widespread use in the food industry, folk medicine as an anti-inflammatory, restorative, antimicrobial agent, the chemical composition of this plant has not been sufficiently studied.Aim. Qualitative and quantitative determination of the main groups of biologically active substances (BAS) in the raw material (leaves) of Elaeagnus argentea growing on the territory of the Astrakhan region for further development of a methodology for standardizing the raw material of this plant.Materials and methods. The leaves of Elaeagnus argentea were harvested in the spring in the eastern part of the delta of the Astrakhan region (Volga region). Drying of raw materials was carried out in natural conditions. In the study, unified methods were used: to determine the amount of flavonoids and saponins, the spectrophotometric method was used, ascorbic acid - the titrimetric method. For the analysis of flavonoids in the leaves of Elaeagnus argentea, an aqueous-alcoholic solution of 70 % concentration was used as an extractant. The quantitative content of flavonoids was determined in the obtained raw material extract in terms of luteolin-7-glucoside. The amount of saponins in the leaves of Elaeagnus argentea was determined in terms of oleanolic acid. 96 % ethanol was used as an extractant. The quantitative determination of ascorbic acid in the aqueous extract of crushed raw materials was carried out by titrimetry based on the ability to reduce 2,6-dichlorophenolindophenol.Results and discussion. In the pharmacognostic study of biologically active substances in the leaves of Elaeagnus argentea, the content of ascorbic acid was found to be at least 0.32 %, the amount of flavonoids in terms of luteolin-7-glucoside was at least 1.92 %; saponins - 2.38 %; which indicates the need for a more detailed study of the phytochemical composition of other morphological groups of the plant Elaeagnus argentea growing in the Astrakhan region.Conclusion. The data obtained during the study can be used to confirm the quality of raw materials (leaves) of Elaeagnus argentea. A more detailed study of leaves for the presence of other groups of biologically active substances will make it possible to use the obtained data for the development of regulatory documents for medicinal plant raw materials «Elaeagnus argentea leaves».

We did a comparative analysis of tea and raw tea materials. There is an increase in the content of carotenoids and flavonoids (thearubigins and theaflavins) in June, a decline in July, and August, and consequently a slight increase again in other months. The increase is due to unfavorable conditions – drought during these periods. In raw new variety forms No. 855 and No. 582, as well as in black tea variety form No. 582 (0.09 mg.g-1), we determined the high value of theaflavins (0.10; 0.11 and 0.09 mg.g-1, respectively). The highest content of thearubigins was found in variety forms No. 582 and No. 3823 (1.33 mg.g-1 and 1.17 mg.g-1). Ascorbic acid is significantly disintegrated (on average 96 – 97%) in the production of black tea. In green tea, ascorbic acid disintegrates to a lesser extent, leaving about 13% of its initial amount in the raw material. The dynamics of GPOD activity in a 3-leaf sprout are variety-specific. At the beginning of the growing season (May), the activity of the enzyme was low – in the range of 0.363 to 0.607 g-unit in sec. In June, there is a decrease in activity, which, however, is not significant (p <0.05) and is due to the biological characteristics of the tea culture. In green tea, the ruthine is on average 3 times more than in black tea (on average about 38.09 and 12.12 mg.100g-1, respectively). We have identified 11 amino acids; the highest percentage accounted for proline (from 30 to 70%), valine (17 – 30%), and serine (about 10%). We have identified 11 amino acids in Krasnodar tea, a large proportion of these amino acids has proline, valine, and serine. There was a variation in the content of biologically active substances depending on genotype characteristics. Studies have identified some controversial issues that require explanation and further study.

Abstract At present, the preservation of the consumer properties of berry products is an urgent problem. Use of fresh garden strawberries is limited by a short storage period and seasonality. Under optimal storage conditions in a normal atmosphere, the average shelf life of strawberries is from 2 to 9 days depending on the variety. To meet the needs of the population in garden strawberries and meet the physiological needs in a unique complex of biologically active substances, strawberries are subjected to different processing methods. Drying being a type of fruit and berry products processing has the following advantages: a significant increase in the shelf life of products, a decrease in the mass and storage volumes of dried berries, preservation of minerals, carbohydrates, dietary fiber, antioxidants, bioflavonoids and many biologically active compounds in berries. Modern drying technologies allow preserving the content of essential vitamins to its full extent. Comparison of two technologies for drying garden strawberries has established that vitamins and other biologically active substances are well preserved in berries. Berries dried by convective vacuum-impulse method (CVI) are recommended to be used for food enrichment.
