The use of local non-conventional raw materials will allow significantly enriching unfortified fruit wines with ascorbic acid and phenolic substances and make it possible to obtain products with increased biological value. The paper considers black elderberries grown in the forest steppe zone of Ukraine. It has been determined that they contain 12–13% of soluble solids, 6.9–8.1 of sugars, 0.93–1.2% of titratable acids, 33.4–53.1 mg/100 g of ascorbic acid, and 2331–3888 mg/100 g of phenolic substances. The pressing process and its dependence on the method of treating berries have been studied. It has been proved that juice extraction from black elderberries is the highest when they are pretreated with heat at 98±2°C for 3–5 minutes, with 15% of water added. Depending on the treatment method, juices retain ascorbic acid (15.8–33.4 mg/100 g) and phenolic substances (2538–3888 mg/100 g), which indicates their high biological value. Juices like these can be used to improve the biological composition of blended juices and wines. To ferment high-sugar black elderberry must, active dry yeast was used, namely the yeast races EC-1118 of the genus Saccharomyces bayanus (France) and ENSIS LE-1 or ENSIS LE-5 of the genus Saccharomyces cerevisiae (Spain). The musts were fermented for 36–62 days. The period of vigorous fermentation coincides with the period of initial fermentation and ends in 9–10 days, with accumulation of 12–14% of ethanol by volume. Unfortified wine materials obtained from black elderberries contain 22–38.3 mg/100 g of ascorbic acid (its content in wine materials is by 7.8–49.55% lower than in fresh berries) and 1750–3510 mg/100 g of phenolic substances (which is lower by 9.7–39.6%, as compared with fresh elderberries). The active acidity of black elderberry wine materials is 3.90–4.09 pH units, depending on the yeast race. A similar difference has been found for the redox potential (160–176 mV), which indicates that the wine materials from black elderberries are low-oxidised. The intensity of colour of the wine materials obtained from black elderberries (D420 + D520) varied from 3.08 to 3.20, and the colour shade from 0.88 to 0.92, which is typical of young red wines. These wine materials can be used to increase the quality and biological value of blended wines.

The results of comparative study of the content of biologically active substances in the aboveground part of 11 species of perennial onions Allium aflatunense B. Fedtsch., A. altaicum Pall., A. flavum L., A. microdictyon Prokh., A. nutans L., A obliquum L., A. ramosum L., A. rosenbachianum Regel, A. schoenoprasum L., A. senescens L. var. glaucum Regel (A. senescens ssp. glaucum (Schrad.) N. Friesen), A. strictum Schrad. are presented. The freshly collected raw materials in the phase of consumer ripeness were analyzed and all indicators, except for the amount of ascorbic acid, were calculated on the mass of absolutely dry raw materials. It was established in onions a high content of dry substances (up to 25.1%), flavonols (up to 3.4%), tannins (up to 14.6%), pectin substances (up to 25.8%), sugars (up to 34.8%), ascorbic acid (up to 222.5 mg% ), carotenoids (up to 131.9 mg%); the content of catechins was insignificant, at the level of 0.04–0.15%, only in A. rosenbachianum – up to 0.56%. The contents of catechins, tannins, pectin substances in onions were determined for the first time. A high interspecific and individual variability of accumulation of biologically active substances was revealed. A. rosenbachianum, A. aflatunense, A. flavum, A. microdictyon have the greatest contents and relatively low indicators are in A. senescens var. glaucum. The species are promising for cultivation in the forest-steppe zone of Western Siberia as early vitamin-bearing plants and as a source of various biologically active compounds.

The object of this research is the interaction of the forest and forest-steppe habitat of Eastern Europe during the Golden Horde. The subject of this research is the interaction of the Chiyalik culture, formed in the forest-steppe zone of Volga-Ural region and the Golden Horde culture formed in the steppe zone of Western Eurasia. The monuments of Chiyalik culture – subsoil burial grounds and ancient settlements – are located in the valleys of the Rivers Kama, Belaya, Ika, Dema, Chermasan, Suni and other rivers in the eastern parts of modern Tatarstan and northwestern parts of the modern Bashkortostan, dating back from XII–XIV centuries. The bearers of Chiyalik culture were Ugric by origin, who have undergone Turkization and Islamization. The article explores the narrative sources that contain records on the relations between Uralic Ugric Peoples and Mongols, archaeological data on the objects of the Golden Horde import found on the monuments of Chiyalik culture. Special attention is given to the comparative analysis of narrative sources and archaeological data on the problem of interaction of Chiyalik culture and the Golden Horde as the synchronous historical phenomena. Narrative sources indicate the conquest of the territory of Chiyalik culture by the Mongols, tribute and labor conscriptions carried out by the local population in favor of the conquerors. The objects of the Golden Horde were detected on the settlement monuments: silver earrings and coins were found in Ufa-II settlement; copper coins were found in Iske–aul settlement; pottery and copper coins were found in Podymalovo-I settlement. Silver Golden Horde coins were found in the Taktalachuk and Azmetyevsky burial grounds. The author’s special contribution to this research lies in the conclusion that the paucity of findings is explained by the absence of large settlements, and the Muslim funeral rite. The novelty consists in establishment of the fact of the unilateral impact of the Golden Horde culture upon the Chiyalik culture: in exchange for the items of the Golden Horde import, were exported the raw materials, items of cattle breeding, hunting and beekeeping.

The morphological variability of the aerial vegetative and generative organs of Melilotus officinalis in the ecotone communities of the forest-steppe zone, the forest zone of the Republic of Tatarstan including desecrated parts of the forest zone was studied. The ascorbic acid content in various parts of the plants growing in these habitats was also analyzed. It was revealed that the realization of the morpho-physiological potential of plants was determined by the conditions of botanical-geographical zones. The sweet clover, growing on black soils under the conditions of ecotone communities of the forest-steppe zone, was found to have higher indicators of “total biomass”, “biomass of leaves”, “biomass of inflorescences”, etc., as compared to the plants from similar communities growing on gray soils of the forest zone. Under the conditions of the ecotone communities of the forest-steppe zone, the content of ascorbic acid in all parts of the plant was also higher. Melilotus officinalis, growing in the conditions of a desecrated soil layer, was characterized by the maximum realization of its biomorphological potential with a low value of the coefficient of variation (CV), which reflected a stronger homogeneity of the samples. In the plants growing under extreme conditions, a sharp increase in the concentration of ascorbic acid in all parts was observed, which could be considered as an important mechanism for the adaptation of the species to survival under conditions of a sharp temperature difference of the substrate. Along with an increase in the generative period, an important component of the species adaptation was the low correlation between the indicator “biomass of inflorescences” and the concentration of ascorbic acid in inflorescences, “biomass of inflorescences” and the concentration of ascorbic acid in the leaves, which reflected the stable process of formation of the generative system of sweet clover. All coenopopulations were characterized by an incomplete ontogenetic spectrum with an absolute maximum on the plants with the middle-age ontogenetic status (95%).

Abstract. Purpose. Heavy metals can have a negative effect on plants, animals and humans if their concentration exceeds certain limits. Therefore, it is important to establish the characteristics of the accumulation of heavy metals and to determine the elemental composition of aboveground (leaves) and underground (bulbs) organs in plant samples of 8 varieties of Narcissus hybridus hort. (Actaea, Arctic Gold, Cassata, Quail, Sir Winston Churchill, White Lady, Calgary, Pink Parasol) and Camassia cusickii S. Wats. in the urbanized environment of the city of Ufa (Republic of Bashkortostan). Methods. The study of the elemental composition of the samples was carried out according to the method of quantitative chemical analysis “Determination of As, Pb, Cd, Sn, Cr, Cu, Fe, Mn and Ni in laboratory samples of food products and food raw materials by the atomic absorption method with electrothermal atomization No. M-02-1009-08”. Scientific novelty. This work is the first to analyze the results of the content of individual elements in aboveground and underground organs in samples of cultivated floral and ornamental plants in the forest-steppe zone of the Bashkir Ural. Results. It was found that the content of nickel, copper, cadmium, lead, magnesium, iron, chromium in all the samples studied does not exceed the standards specified in the State Pharmacopoeia of the Russian Federation (SP RF). The arsenic content exceeds the standards specified in the SP RF by 3.4 times. Revealed a high intensity of biological absorption of copper. The peculiarity of the accumulation of individual elements by different taxa of the studied plants is noted. It has been established that the concentrations of As, Cu, Pl, Mn, Fe in the aboveground organs are higher than in the underground part of plants; the ratio of the content of Ni, Cr, Cd in aboveground and underground organs is the same. As a result of these studies, it was recommended to use the studied cultivars as a phytoremediator of arsenic.

The growth of the essential oils market is explained by the growing demand for natural and organic products. Today, the global aromatherapy market with essential oils is growing, and demand for essential oils is increasing at the same rate. The studies are dedicated to the valuable essential oil culture ‒ fennel, the spread of which in the forest-steppe zone of Ukraine will allow to obtain high profitability by agro-forming of different forms of ownership and will help to provide the Ukrainian market with raw materials of appropriate quality. The article offers a solution to the pressing issue of expanding the area of new unconventional culture in the conditions of the Forest-Steppe of Ukraine by improving technological measures in the cultivation of culture. The basis of scientific research is the study of sowing terms (1st decade of April, for soil LTR 6-80C), (2nd decade of April, for LTR of soil 10-120C); row spacing (5, 30, 45 and 60 cm) and seeding rates (1, 1.5 and 2 million sprouting seeds per hectare). Among the plans of the research tasks were: to conduct the accounting of yields and to determine indicators of seeds quality (the content of essential oil in fennel seeds and its conditional yield per hectare of sowing), depending on the studied factors. Crop accounting was performed by continuous submerged threshing. The yield was brought to 100% purity and standard humidity according to the method described by V.O. Moiseychenko and V.O. Yeshchenko. Mathematical data processing was performed according to the method of B.A. Dopehova. The results of the research show that the sowing variants in the first decade of April, with a wide-row method (45 cm) sowing rate of one million sprouting seeds per hectare, yielded the optimum yield of fennel – 1.48 t / ha. In the same variant, the maximum content of essential oil was obtained – 6.23% and its yield from the hectare sowing area‒ 59.2 kg.

Abstract Wood is a material with unique properties that contribute to its wide use as a raw material for various types of industries. Different quality requirements are imposed on the raw materialdepending on the material or wood product. However, physical and mechanical properties of wood are not homogenousalong the radius and height of the trunk and depend on the species, location in the trunk and growing conditions. The aim of this research is to study the variability of porosity and density of Scots pine (Pinus sylvestris L.) wood in a tree trunk growing in dry forests of the forest-steppe zone of the Russian Federation. The studies were carried out on wood cuts, sawn at different trunk heights. The change in the density of pine wood along the height of the trunk by 1.43% for each meter has been established. The wood porosity increases from the butt to the top by an average of 5.5%. New information about the variability of wood properties makes it possible to rationally and reasonably approach the choice of raw materials for obtaining materials with specified performance characteristics.

The purpose of the work is to study the permissible distance for the collection of medicinal plant raw materials near transport highways of different degrees of loading. The study was carried out in the Voronezh region on the example of eight different types of medicinal vegetable raw materials (Herring grass bitter, avian mountain grass, five-foot desert grass, plain thousand-year-old grass, double-ground nettle leaves, large planter leaves, common pajma flowers, core lip flowers) Collected in time of procurement along and at different distance from roads and railways of different degree of load in different natural zones, regulated by normative documentation. In the analyzed samples, the content of standardized biologically active substances, as well as heavy metals, pesticides, radionuclides, was previously estimated and full compliance with pharmacopoeia requirements was shown. In this work, the analysis was carried out on the level of ash insoluble in hydrochloric acid in the medicinal plant raw material, which makes it possible to estimate contamination of the raw material with dust particles. On the basis of the obtained data using the mathematical simulation method, the permissible distances from the transport lines, which can be recommended for the collection of safe medicinal plant raw materials, have been identified: Distance from major roads and highways loaded by road in forest natural zone conditions – at least 230 m, in forest steppe zone conditions – at least 300 m, in steppe zone conditions devoid of wood and shrub vegetation, – Not less than 660 m, near non-high-speed roads characterized by low traffic load – not less than 160 m, near railway lines – not less than 130 m. The obtained results can be recommended for safe collection of medicinal vegetable raw materials.

Studies of the effect of antimicrobial agents on the conservation of broccoli cabbage have been conducted. The late hybrids of broccoli Ironman F1, Agassi F1, Beaumont F1, grown under the conditions of the Forest-Steppe of Ukraine were studied. The content of the main components of the chemical composition (dry substances, dry soluble substances, sugars, vitamin C) of broccoli cabbage is analyzed depending on the characteristics of the hybrid. The effect of antimicrobial treatment on the natural loss of cabbage, microbiological lesions during storage has been studied. Antimicrobial preparations Baikal EM-1 (dilution of working solution in water 1: 500), 0.5 % solution of citric, 0.2 % benzoic, 0.05 % sorbic acid, and also 0.5:0.5 % solution of vitamins C and P (ascorutin), water for the preparation of solutions had a temperature of 23 ... 25 °C. The processing of fruit and vegetable products with various chemicals is aimed at prolonging the shelf life, increasing the shelf life and increasing the yield of commercial products at the end of storage. It is established that the natural loss of broccoli cabbage during storage depends on the characteristics of the hybrid and the type of antimicrobial preparation. Treatment with preparations increases the shelf life of broccoli cabbage to 30 - 50 days with a natural weight loss of up to 6.1 %, and ensures minimal disease burden. Treatment with antimicrobial agents reduces the loss of dry substances, dry soluble substances, sugars, vitamin C. The most effective is the treatment of broccoli with acids. It has been established that ascorbic acid is contained in broccoli cabbage, with hydrolysis from which ascorbic acid is split off, the content of which is increased. The maximum effective storage of broccoli cabbage at a temperature of 0 ± 1 oС and relative humidity of 90-95 %, pretreatment with preparations of antimicrobial action. The proposed method of processing broccoli cabbage with antimicrobial preparations before storage allows the use of vegetable raw materials for post-harvest treatment. In the development of new, low-cost, environmentally friendly and affordable storage technologies, this is an important technique.

The content of ascorbic acid and phenolic substances in natural juices and unfortified wine materials from garden strawberries of Polka and Pegas varieties was investigated. The content of ascorbic acid was 271-417 mg/dm3 and of phenolic substances – 1280-1500 mg/dm3. The content of these ingredients depends on the variety characteristics (dominant influence) and the weather conditions of the growing season. 230 g of white sugar was added to one dm3 of strawberry juice for the production of unfortified wine materials intended for sweet wines. The wort was pasteurized at 85°C for 5 minutes, cooled and fermented using active dry yeast: the race EC 1118 (France), ENSIS LE-C1, ENSIS LE-1, ENSIS LE-5, ENSIS LE-6 (Spain) in accordance with the manufacturer's recommendations. It has been found that the content of ascorbic acid and phenolic substances decreases during wort preparation and fermentation. The average loss of ascorbic acid during wort preparation is 17.4% and of phenolic substances – from 1.1 to 4.9%. The reduction in the content of these components due to the dilution of sugar during wort preparation is 14-15%. The duration of fermentation of strawberry worts with an initial mass concentration of invert sugars 274 g/ dm3 is 70-77 days. The output of cleared wine material after fermentation depends on the variety characteristics, the year conditions and the yeast race used, and ranges from 86.9 to 92.7%. Loss of ascorbic acid during wort fermentation averages 49.3%, phenolic substances 21.6%. Ascorbic acid content of 86-158 mg/dm3 and phenolic substances of 720–1080 mg/dm3 were found in unfortified strawberry wines. In particular, according to the average data of two years, the content of phenolic substances in the wine materials from strawberries of the Polka variety were 197 mg/dm3 higher than their content in the wine materials from the berries of the Pegas variety. The content of ascorbic acid in wine materials in relation to the content in the juices corresponding to fresh berries is 25.4-41.3%, on average – 33.6%; of phenolic substances – 56.2-72.0%, on average 62.6%. In order to better preserve the ascorbic acid, the ENSISLE-C1 yeast race (Spain) and the phenolic substances EC-1118 (France) should be used. The results of studies confirm that unfortified sweet wines from wild strawberries can be attributed to the products with health-promoting properties.
