In urological practice there is a sufficient demand for herbal medicinal preparations, of which the most widely used drugs are derived from arbutin-containing herbs. These medicines have diuretic, anti-inflammatory and antimicrobial activity. Currently, in connection with the decrease in number of production departments and pharmacies, water extraction can be made by the consumer at home from powdered medicinal herbs in filter bags and from packaged shredded medicinal plant raw materials in batches according to the instructions on the package. The object of the study was the aqueous extract obtained from the leaves of lingonberry. The article presents the study of manufacturing technology of water extracts from lingonberry leaves with the establishment of quality indicators in them. Investigated water extract obtained from raw materials packaged in bundles according to the instructions on the package, filter packages according to the instructions on the packaging of packaged raw materials in batches according to the method of State Pharmacopea XIII. The following were analyzed in the obtained water extracts: description, authenticity, dry residue, pH, content of phenolglucoside - arbutin. The research results were processed statistically. All of the studied aqueous extracts were transparent dark brown liquid that had a bitter, astringent taste characteristic of leaves of lingonberry. Dry residue in an aqueous extract, depending on the composition and technology was 0,65, 0,8% and of 1,93%. The content of arbutin was 0,43, 0,39 and 0,99%, pH of water extracts made from the crushed leaves of lingonberry, had close values of 5,03, 4,95 and, while in the extracts from powdered of lingonberry leaves in filter bags had pH value of 5,35, which may be attributed to the influence of the material of the filter bag. For the first time technologo-analytical study of the water extracts obtained at different technologies, established indicators of quality.

Daily food consumption norms of an average woman and a pregnant woman have been analysed. It has been established that in a pregnant woman’s diet, it is necessary to increase the content of proteins, fibre, vitamins C, E, D, PP, and B, and reduce fats, carbohydrates (easily digestible), vitamins B5 and H, sodium, magnesium, salts, and water. Taking into account the above-mentioned requirements, eight recipe compositions of sweet ices based on plant raw materials have been suggested. The recipes were selected by linear programming using MS Excel. The products have a low calorific content (26–137 kcal per 80 g), and an increased nutritional value (due to vitamin C, carotene, etc.). For the first time, cereals, various types of seeds, nuts, have been put into the recipe of sweet ices, as well as raw materials, which eliminate physiological complications during pregnancy. The products developed differ in their composition and are made without sugar. However, some recipes include small quantities of honey as it is highly palatable. The chemical composition of the new sweet products has been studied and analysed in details and sugar/acid indices have been calculated. The developed ices have a slightly acidic taste or no acidity at all, which corresponds to the values of sugar/acid indices 13.4–26.6, while the sample from the store, selected for comparison, contains a large amount of sugars, as evidenced by the cloying taste and high sugar/acid index (more than 30). The source of fatty acids in sweet ice for pregnant women Joy is almond nuts. The results of the chromatographic study have shown that this product as for the quantitative fatty acid composition, meets the current requirements. We recommend introducing the sweet ice manufacture technology on the equipment already in use in canneries. The products are formed (poured into moulds where wooden sticks are then inserted) in a Hassia machine. One of the main operations, freezing, is done in a quick freezer GyroFreze. We also recommend manufacturing sweet ices using existing restaurant equipment.

The article presents materials on the isolation of ecdysterone substance from medicinal plant raw materials Silene wolgensis (Hornem.) Bess. ex. Spreng (Volga smolyovka). For the first time, the optimization of the method for ecdysterone substance obtaining from the aboveground part of the superconcentrator of phytoecdysteroids of the Silene wolgensis was carried out and based on it a pilot industrial regulation for the isolation of ecdysterone and an encapsulated water-soluble form were developed. It was found, that the interaction of the substrate molecule and the clathrate forms a substance that can dissolve in water and other more polar solvents, thereby solving the problem of bioavailability of the main hydrophobic drug. The method developed for producing the substance ecdysterone and its water-soluble encapsulated with β-cyclodextrin form was implemented into production at the Karaganda pharmaceutical plant. NMR studies of changes in the chemical shifts of protons of substrates and receptors illustrated that ecdysterone interacts with β-cyclodextrin to form supramolecular inclusion complexes with stoichiometric composition of 1:1

Aim. To study extractability of a complex of active and related substances and flavonoids from St. Johns Wort herb of various series and anufacturers and identification of factors affecting the quality of aqueous extracts from St. Johns Wort herb. Materials and Methods. The object of study was St. Johns Wort herb of four series of two manufacturers, and aqueous extracts obtained from these series of St. Johns Wort herb. Aqueous extracts were made in the infusion mode in accordance with the requirements of the Order of the Ministry of Health of the Russian Federation №751n of October 26, 2015. The ratio of raw materials and extractive solvent was 8:100. The obtained aqueous extracts were evaluated by color and smell parameters. A complex of biologically active and related substances extracted from St. Johns Wort herb was evaluated by the solid residue index. Quantitative determination of flavonoids in recalculation for rutin was performed by spectrophotometric method on Bio-RADSmartSpecPlus spectrophotometer at 410 nm wave length. Results. Raw materials of different series differ in external characteristics and fineness. Raw materials of 221218 series contain 17.46% of particles larger than 3 mm, and raw materials of 20218 series – 4.92%. Raw materials of 221218 series include more particles of the coarse parts of the plant. Raw materials of 10119 series have a more uniform distribution of particles by fractions, but a rather large number of small particles. The maximal solid residue was obtained from raw materials of 20218 series – 1.7716%, the minimal – from raw materials of 221218 series – 0.6183%. The maximal flavonoid content was found in aqueous extract obtained from raw materials of 20218 series – 1.988%, the minimal content – from raw materials of 221218 series – 0.6183%. A sufficiently high yield of flavonoids in the aqueous extract was established for raw materials of 10119 series – 1.9711%. Conclusions. It was found that raw materials containing more soft parts of plants and characterized by the presence of a higher percent of fine fractions of particles, have the best extractability. At present, in the SP (Russia) of the 14th edition, only fractions of St. Johns Wort herb with a particle size of more than 7 mm and less than 0.18 mm are normalized. In our opinion, it is reasonable to include requirements to particle size and their content for the main fractions of the feedstock.

The buds of horse chestnut (Aesculus hippocastanum L., Hippocastanaceae family) is a new promising species of medicinal plant raw material. The prospect of studying the buds of this plant is due to the content of flavonoids in them, which have a wide range of pharmacological effects. Flavonoids are interesting for their capillary-strengthening action, which allows them to be used in the treatment of chronic venous insufficiency. This fact is consistent with the practice of using drugs from other organs of horse chestnut (seeds, leaves) as venotonic and angioprotective drugs. In addition, flavonoids are also characterized by antioxidant, anti-inflammatory, antimicrobial and antifungal activity. The actuality of the study of horse chestnut buds as a new type of medicinal plant material is also supported by the need to develop of the new effective and safe drugs based on the raw materials of this plant. The aim of this study was to determine the flavonoid composition of the buds of Aesulus hippocastanum. In the course of the work from the buds of horse chestnut by the method of column chromatography on silica gel L 100/160 was for the first time there were isolated and characterized using 1H-NMR, 13C-NMR, UV spectroscopy and mass spectrometry the flavonoid compounds rhamnocitrin (7-O-methylkaempferol), and accompanying 7,4′-dimethylkaempferol. The dominant and diagnostic significant flavonoid for the horse chestnut buds is rhamnocitrin. The results indicate the prospects for further study of the buds of the horse chestnut as a new type of medicinal plant raw materials.

The relevance of the study of the mineral composition of plant objects is undoubted. In plant organisms, macro and micronutrients are present in an easily digestible form. The macroelements most accumulated in plants include calcium and magnesium, whose sources are members of the family Polygonaceae Juss, in particular the genus Persicaria Mill. The aim of the work was to develop a technique for quantitative complexometric determination of calcium and magnesium in plant raw materials after the burning procedure and its validation. As a result, optimal conditions for the quantitative determination of calcium and magnesium in plant objects were experimentally selected using the example of Persicaria maculosa Gray. mountaineer grass using complexometric titration after ashing and calcination. For the determination of calcium, the optimum pH value is 11–12, the acidic indicator is dark blue – chromium, the optimum pH for magnesium is 8–9, the indicator is pyrocatechol violet. The calcium content in the plant varies from 0.12% to 0.58%, the amount of magnesium is about 0.02%. The relative error of the mean determination with a 95% probability was no more than 1.60% and no more than 1.84% when determining calcium and magnesium, respectively. Studies have shown the validity of the developed methodology for indicators of authenticity, precision (convergence, reproducibility), specificity, linearity.
