The degree of variability in the composition of herbal medicines was studied on the example of the preparation of St. John's wort from various Ukrainian producers. The Cu and Zn contents were the most stable compared to other (Fe, Mn, Co, Cr, Ni, Pb, Cd) microelements among plants of different origins. The content of toxic elements (Pb, Cd) did not exceed the established standards. Meanwhile, a 2-3-fold concentration difference was observed for hyperforin, an active pharmaceutical ingredient in St. John’s wort. Thus, the existing standards do not ensure the stability of the composition of herbal preparations. As a result, the quality of medicinal drugs can be significantly different. The key reason for the variation in plant composition is environmental influence, including anthropogenic factors. Existing training programs for prospective specialists of the pharmaceutical industry do not pay enough attention to the impact of the environment on the quality of herbal raw materials. Necessary changes to the syllabi of relevant disciplines are formulated to eliminate this shortcoming and ensure sustainable development of raw materials sources for the pharmaceutical industry.

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.


Domiati cheese is the most popular brand of cheese ripened in brine in the Middle East in terms of consumed quantities. This study was performed to investigate the impact of the microbiological quality of the used raw materials, the applied traditional processing techniques and ripening period on the quality and safety of the produced cheese. Three hundred random composite samples were collected from three factories at Fayoum Governorate, Egypt. Collected samples represent twenty-five each of: raw milk, table salt, calf rennet, microbial rennet, water, environmental air, whey, fresh cheese, ripened cheese & swabs from: worker hands; cheese molds and utensils; tanks. All samples were examined microbiologically for Standard Plate Count (SPC), coliforms count, Staphylococcus aureus (S. aureus) count, total yeast & mould count, presence of E. coli, Salmonellae and Listeria monocytogenes (L. monocytogenes). The mean value of SPC, coliforms, S. aureus and total yeast & mould counts ranged from (79×102 CFU/m3 for air to 13×108 CFU/g for fresh cheese), (7×102 MPN/ cm2 for tank swabs to 80×106 MPN/ml for raw milk), (9×102 CFU/g for salt to 69×106 CFU/g for fresh cheese) and (2×102 CFU/cm2 for hand swabs to 60×104 CFU/g for fresh cheese), respectively. Whereas, E. coli, Salmonella and L. monocytogenes failed to be detected in all examined samples. There were significant differences in all determined microbiological parameters (p ≤0.05) between fresh and ripened cheese which may be attributed to different adverse conditions such as water activity, pH, salt content and temperature carried out to improve the quality of the product.

Efficient utilization of multi-tonnage oil sludge is one of the most pressing environmental problems. Since natural raw materials are currently depleted, it is necessary to involve oil sludge in the production turnover for the production of lightweight bricks. At the same time, the costs of geological exploration, construction and operation of quarries are excluded, and significant land plots are exempt from the impact of negative anthropogenic factors. Waste from oil production with an increased content of calorific value is advisable to use not only as a thinning agent, but also as burn-out additives for the production of thermal insulation materials, which include lightweight bricks. A lightweight brick, which belongs to class B with high physical and mechanical properties, was obtained.

Abstract Today, the search for new antibacterial natural agents based on plant raw materials is relevant. These raw materials have promising secondary metabolites that reduce the formation of methane in the ruminant scar. The aim of this study was to evaluate the effect of the following extracts: oak bark+birch leaves (I group) (250 ml/head per day), oak bark + St. John’s wort grass (250 ml / head per day; II group) and birch leaves + St. John’s wort grass (III group; 250 ml/head per day) on the rumen microbiota of large cattle, against the background of control (C). Extracts added to the water of calves with rumen fistula (dairy breed, age 12 months, diet -70 % of hay, 30 % of grain feed, duration is 14 days). The microflora analyzed using high efficiency 16S rRNA (Illumina) gene sequencing. Plant extracts prepared by purification, grinding (1–2 mm) and extraction in a water bath (for 30 min, 70 ° C) and filtration. According to the study results, the inclusion of extracts led to increase of the Bacteroidetes phylum for 1.11–3.69 % in the practical groups in comparison with C. A decrease was obtained for Firmicutes for 2.06–3.55 % (p 0.05) and Proteobacteria. In the I group bacteria of the class Bacteroides increased by 0.9–5.64% and Candidatus Saccharibacteria increased by 0.25% (P = 0.05). In the III group the value increased by 0.64 % (P = 0.05). Compared to C at the level of the family Prevotellaceae dominated in all experimental groups by 1.04–9.11 % (P ≤ 0.05), in group III Bacteroidaceae dominated by 0.27 % and Rikenellaceae by 0.14 %. This contributes to the regulation of opportunistic microorganisms without harmful effects on the rumen microbiota. This research was performed with financial support from the project 0761-2019-0005.

Two experiments were conducted in the province of Ñuble, Chile during the 1997/98 and 1998/99 seasons with the objective of evaluating the effect of harvesting date on the yield and quality of St. John's wort (Hypericum perforatum L.) in the second year of production. The apical 25 cm of the stem were harvested in the following stages: flower bud, beginning of flowering, full flower and petal drop. A randomized complete block design with four replications was used. The best yield (fresh, dry and threshing weight) and the highest hypericin content were obtained at the petal drop stage. Nevertheless, the results indicate that the best time to harvest St. John's wort is when 10 to 20% of the flowers are open and the rest are in the bud stage.

The formation of fiber flax yield and quality parameters depends on many soil-climatic, breedinggenetic, as well as anthropogenic factors. The quality of flax fiber is a combination of a number of features and properties that depend on the varietal characteristics of plants, the conditions of their cultivation, technologies for harvesting and straw retting, as well as on the processing modes of raw materials. During plant vegetation (90-130 days) many factors such as soil conditions (pH 4.8-5.5, humus 1.8-2.5%, P2O5 and K2O – 150-200 and 100-200 mg/kg, respectively) and the area of plant nutrition (15-30 million seeds/ha), temperature regime (the sum of active temperatures 1000-1800ºC), water supplying (400-430 units of water mass to create 1 unit of dry matter) and insolation (the arrival of FAR during the growing season 20-25 kcal / cm²), contamination of weeds (more than 60 annual and perennial species) and pests (more than 200 types of fungal, bacterial and viral diseases), features of phytosanitary measures (more than 50 chemicals) and agrotechnologic manners (Federal Register of technologies for the production of crop products) have a great influence on the quality of flax raw materials and can be a limit factor. Environmentally hazardous pollution of air, water and soil - the main components for the production of fiber flax – strongly affects the yield and quality of flax products. The development of waste-free environmentally friendly technologies for the cultivation, harvesting and processing of flax is an urgent task of scientific support of the industry. The main environmental factors affecting the yield and quality of fiber flax are discussed in the article.

The Food and Drug Administration (FDA) is advising consumers to stop using multiple weight-loss products that contain the undeclared drug ingredients e.g. sibutramine, which was removed from the market in 2010 for safety reasons and may present significant risks for those with coronary artery disease and other heart issues. Sibutramine and similar undeclared ingredients in herbal medicines are a real challenge for the public health and safety. In recent years, the need for quality assurance tools to ensure the identity, purity, and quality of botanical material has risen dramatically. HPTLC has emerged as a versatile, high throughput, and cost-effective technology, that is uniquely suited to meet these requirements. Most separation techniques do not allow parallel analysis of numerous samples at the same time and they often face problems in separating complex mixtures of substances. However, visual evaluation of HPTLC plates allows for convenient comparison of many samples side by side, where similarities and differences can clearly be seen. The quality of raw materials is rapidly and easily determined by HPTLC. For the identification of herbal drugs and other naturally derived materials standardized HPTLC is the method of choice and recommended by pharmacopoeias worldwide, furthermore adulterated samples are reliably identified. The main objective of the present study is to check pharmaceutical analogue adulteration of nonprescription and prescription slimming products in the laboratory using chromatographic techniques and to discuss its side effects in the interest of consumers and public health safety. Since intentional adulteration of “natural herbalmedicines” with unknown synthetic drugs or chemicals is a common and dangerous phenomenon of alternative medicine, it is important to modify and validate analytical tools to monitor and evaluate these herbal drugs.

The book presents the path of production development of honey wine, from the times of Kievan Rus to the present. A deep analysis of culture, honey winemaking, one of the best in its time in world practice, shows what heights were achieved, and how more than a century ago this art was lost. There were many different unsubstantiated sentences, primitive literature, in no way restoring the glory of our great ancestors and not meeting modern requirements for making wines in general. In the last century, as in the entire post-Soviet space, and in Ukraine, the use of honey in winemaking was prohibited and there were ao standard documents on its use for this purpose. The author, with the support of the country's government, while fulfilling the task of the Cabinet of Ministers of Ukraine to improve the quality of fruit and berry wines, produced at that time, it was possible to convince the country's leadership of the need to use honey for the preparation of high-quality honey fruit and berry wines. For this purpose, technical conditions TUU 202.13.022-99 were proposed, developed, and approved "Fruit and berry dessert wines with aromatic additives", where, in addition to the use of fruit and berry, spicy, aromatic, and medicinal raw materials, the use of honey was first laid. For the first time according to TUU, a number of honey wines were developed, approved, and mastered in produccion. At international competicions, such wines have received the highest awards, gold medals, and Grand Prix cups. Subsequently, with the participation of the largest scientific centers, GOST (DSTU 6036: 2008) was prepared. Fruit and berry wines, general technical conditions, in which the production of honey wines arc separated into another group. These regulatory documents fully regulate the production, release, and quality control of honey wines in Ukraine. The author offers a broad overview of the basic terrns and designations necessary for the production of high-quality fruit and berry honey wines. Provides and explains the modem requirements for the classification of honey wines, measures on safety, sanitation, and hygiene are seriously discussed, analyzes the main conditions and factors that detennine the quality of the necessary components, and the preparation of honey wines in general. Since honey wines can only be prepared using fruit and berry wines, including grape juices, the book provides the necessary overview in the processing of fruits, berries, grapes, the reception and quality control of raw materials, and the preparation of juices. Very important and inforrnative material is presented in the chapters on the selection and procurement of honey, for the preparation of honey fruit and berry and honey grape wines. Important sections on the impact of wine on the health and culn,re of wine consumption. The most common diseases and disadvantages of honey wines are described. A very informative and impressive list of honey wines, first developed in Ukraine under the guidance of the author, professor, doctor, technical sciences, Laureate of the State Prize of Ukraine in the field of science and technology Litovchentko A.M., in the amount of 48 items, practically from all raw materials available in Ukraine. To facilitate the work on the preparation of high-quality honey wines, 12 additional applications are presented, providing the main technological process of production. The book is of important practical, theoretical, and scientific interest.
