Annotation: The development of extraction techniques of medical plants aims to maximize the bioactive compounds production. Тechnologies in this area of industry have not high enough еfficiency factor. In some cases, it reaches only 40-50 %. Therefore, development of new methods to effectively extract different compounds from plant material and their input into large-scale industry is of great importance. The goal is to determine an effective and suitable technology for extracting bioactive compounds from medical plant. This is a narrative review paper which focuses on different extraction methods of medical plant. To find relevant articles for this narrative review, 73 articles were reviewed. Of these, 14 irrelevant documents were discarded. This review analyses various extraction processes to guide the selection of suitable methods for various types of medical plants and applications. This is done by outlining traditional and modern methods of extraction techniques, exploring the importance of solvents for extraction, and comparing novel and alternative methods of extraction. In conclusion, based on the current knowledge, solvent extraction is the most common method for medical plants extraction. Enzymatic hydrolysis and supercritical extraction are advanced techniques with high yield of compounds. However, more research is needed for some modern extraction methods.

Annotation: Main problem: The development of the genetic potential of poultry, as well as the receipt of high-quality eggs for collection or further incubation, are possible only if rational and correct feeding of the broodstock and, more importantly, the young during its rearing period is observed. During this period, high-quality protein nutrition occupies an important place, which determines the level of productivity, stable growth, reproductive ability of the bird, as well as the state of health during the feeding period. Protein deficiency always remains an urgent problem for agricultural land, whose main activity is aimed at breeding dairy and meat animals. In this regard, research in the field of finding the use of non-traditional protein feed is of great need. If we summarize the modern achievements in the field of protein and aminoacid nutrition of poultry, we can find the most profitable way to obtain feed additives in industrial production. The studies, the results of which will be described in this article, are aimed at studying the possibility, experimental substantiation of the optimal dosage and the effectiveness of using the feed additive from crustaceans Artemia salina in the diets of chickens of the egg-meat direction of productivity [1]. Purpose: To study the possibility, experimental substantiation of the optimal dosage and the effectiveness of the use of the feed additive from crustaceans Artemia salina in the diet of chickens of the egg-meat direction of productivity. Methods: Analysis and generalization of theoretical information Results and their significance: This article presents the results of the analysis and generalization of theoretical material. The theoretical significance is determined by the fact that it is invested in scientific and practical problems related directly to solving urgent problems, increasing the efficiency, competitiveness and quality of domestic poultry products.
