Relevance. Currently, there is an increased interest in medicinal plants and preparations from natural herbal raw materials. This is due to the fact that biologically active substances of plants are more easily included in vital processes and do not cause side effects in humans. They can be products of primary (vitamins, fats, carbohydrates, proteins) and secondary biosynthesis (alkaloids, glycosides, tannins). Plants always contain a complex of biologically active substances, but one or several have a therapeutic and prophylactic effect. They are classified as active ingredients and are used in the production of medicines. Some of the promising medicinal plants are species from the genus Dioscorea, for example, Dioscorea alata L., containing a complex of biologically active substances. The aim of this work is to study the effect of humidity and the level of mineral nutrition in the root environment on the accumulation of biologically active compounds in the tubers of the dioscorea winged plant, adapted to in vivo conditions on an ion-exchange substrate of various chemical composition and agrophysical properties.Results. It has been shown that Dioscorea alata L. plants are able to accumulate the greatest amount of starch, dry matter, ascorbic acid, and flavonoids in an ion-exchange substrate modified with 1 g/l of the coarse hydrogel fraction. The data obtained can be used for practical purposes.

Nowadays biologically active substances in medicinal plants of Kalmykia are poorly studied. Thus biochemical properties of medicinal plants of the arid territories of the North-Western Caspian region have been studied for the first time. Study of intraspecific variability allowed to determine the influence of growing conditions on the accumulation of biologically active substances and microelements in medicinal plants, that grow in Kalmykia. In this regard, as the alkaloid, flavonoid and tannin content has been shown, approaches of application of known medicinal plants and searching for new raw materials should be reconsidered. This work is a part of comprehensive resource investigation focused on the research in the aim to find rational application of plant growing in Caspian and Volga regions. On the natural forage lands of Kalmykia, alkaloid-bearing plants can be found; they are poisonous to animals, and their number and abundance are directly dependent on anthropogenic pressure. Anabasis, harmalа and ephedra, that grow on the Caspian lowland, contain all groups of studied substances: alkaloids, flavonoids, tannins and extractives. The conducted research shows that alkaloid plants might be used as medicinal plant raw materials. In Anabasis, the total alkaloid content reaches 1.26% in summer and 1.44% in autumn. Percentage of peganin in Harmala grass, stem and root, is about 4.04%, 0.31% and 0.21% respectively while the total amount of alkaloids in harmala exceeds 5.0%. Tannin content is quite high in Anabasis and harmala, as the presence of tannins is a characteristic feature of ephemera. The composition of plant extractives includes all water-soluble biologically active substances: carbohydrates, vitamins, flavonoids, etc., content of the chemicals is high in both Anabasis and harmal. Accumulation occurs even regardless of the season, place of growth in the whole plant.

The cultivation of medicinal plants is currently the main way of providing the pharmaceutical industry with raw materials for obtaining biologically active substances for the production of drugs. The use of natural resources of wild species is decreasing every year for a number of reasons, the biotechnological method has not been properly expanded yet, and in some cases it is possible to reproduce only a part of the complex of target biologically active substances contained in an intact plant. In recent years, a positive growth trend has been outlined in the domestic production of medicinal starting materials of herbal origin. However, there are a number of problematic issues that inhibit the development of medicinal plant growing and lead to a certain stagnation. These are general legislative and organizational problems, as well as deterioration or deficiency of material resources – basic production assets, lack of comprehensive mechanization, shortage of qualified specialists and a number of other obstacles. Nevertheless, the actively growing demand for high-quality raw materials from medicinal plant both in our country and abroad opens up great prospects for the development of medicinal plant production. It should be noted that the analysis of the current state of collection and cultivation of medicinal plants in Russia is poorly developed or is practically absent. The paper examines the current state of medicinal plant production; attempts are made to identify the main problems and possible growth points. Finding solutions to the problems and using the growth points show promise for the transformation of medicinal plant production into an industry with a large import substituting and export potential.

Background. The deficiency of essential nutrients in the human body is the root cause of reduced efficiency, general resistance of the body to various diseases. That is an urgent problem in the context of the spread of coronavirus infection. In this regard, the search for opportunities to meet the needs of the population in food products that contain biologically active substances (BAS) through the use of high-value and at the same time available plant raw materials is extremely important. Marigolds attract special attention among such raw materials. The aim of the work is to study the chemical composition and evaluate the consumer properties of Tagetes L. varieties, zoned in the Kiev region, to prove the possibility of increasing the biological value of pasta by adding to their recipe powder from marigold inflorescences. Materials and methods. The object of research is pasta of B group (noodles). Inflorescences of marigolds of different varieties gathered during the flowering period in July-September 2019–2020 in the territory of Vasylkiv and Obukhiv districts of Kyiv region, Ukraine were used as enriching plant raw materials. The quality of finished pasta was assessed by organoleptic and physicochemical indexes (moisture content and titratable acidity). The content of mineral elements in the fine powder of marigold inflorescences was determined on the EXHERT-3L device, the quantitative composition and BAS identification – by spectrophotometric analysis on the device Specord-200 Analytic Jena UV-vis. The integrated quality index of pasta products was calculated taking into account the importance factors of individual indexes. Results. Comparing the obtained results, we can state that all the studied varieties – Gold Kopfen, Orange Flame, Hawaii, Equinox are characterized by high biological value, regardless of the area of collection. As a result of calculated and experimental studies it was determined that the addition of 7 % of the supplement does not provide the required supply of vitamins and minerals. Replacing the flour in the recipe by 20 % significantly improves the mineral composition, but deteriorates the taste and aromatic properties of pasta. The most optimal and rational amount of added additive is 15 %, as it improves the organoleptic properties of pasta and enriches their BAS. Conclusion. The usage of non-traditional vegetable raw materials, in particular powder from marigold inflorescences, which is rich in biologically active substances, allows not only to expand the range, improve the quality of finished products, but also increase the biological value of the product. The optimal amount of additive –powder from marigold inflorescences, was defined. It is 15 % by weight of flour in the production of noodles. This concentration allows not only to improve the organoleptic properties, but also to increase the content of biologically active substances – vitamins, micro- and macronutrients. The usage of non-traditional natural raw materials (powder from marigold inflorescences) allows to abandon artificial colorsand give the finished pasta a pleasant colorand aroma.

The review summarizes data on biologically active compounds of Achillea nobilis L. and methods of their isolation. From Achillea nobilis L., collected in different places of growth, the following have been isolated: essential oil, the main components of which are monoterpene compounds; sesquiterpene lactones estafiatin, hanphyllin, anobin, chrysartemine A, canin, anolide and tanapartin-β-peroxide; the steroid acetyleucanbin; flavonoids: 3,5-dihydroxy-6,7,8-trimethoxyflavone, 5-hydroxy-3,6,7,4’-tetramethoxyflavone and 5,3’-di-hydroxy-3,6,7,4’-tetramethoxyflavone. It has been determined that the component composition of the essen-tial oil of Achillea nobilis L. largely depends on the soil and climatic factors in the places of its growth, the phase of the growing season and the method of its extraction from plant raw materials, and the extractant used (chloroform, ethanol, hot water, diethyl ether). Antibacterial, antimicrobial, antioxidant, antiparasitic activi-ties are characteristic both for the sums of extractive substances from Achillea nobilis L. and for individual compounds isolated from them. Methods for the isolation of biologically active substances from Achillea nobilis L. for the development of new drug substances are described. The main aim of this work was a com-parative analysis of the available research results on the phytochemical study of Achillea nobilis L.

For correctly assess the effectiveness and safety of the use of sorption-detoxifying agents and feed additives intended for animals receiving feed with an excess content of toxicants, it is necessary to take into account the background levels of radionuclides, toxic elements, pesticides and other technogenic and natural pollutants in the studied substances. The need for such studies is due both to the existence of areas with a naturally elevated level of natural toxicants in the sources of raw materials for the production of additives and drugs, and to the increasing anthropogenic influence, accompanied by the entry of xenobiotics into environmental objects. In series of radiometric studies, the specific activity of technogenic and natural radioactive isotopes (90Sr, 137Cs, 40К, 226Ra, 232Th) in a number of sorption-detoxifying and biologically active substances and preparations used in animal husbandry and veterinary medicine as part of feed additives and pharmacological agents was determined. It was found that in 43% of the studied samples, the level of specific activity of 1,1Sr in 3-90 times higher than allowed by the current standards. The maximum level of 90Sr, equal to (137±9) Bq/kg, was detected in perlite. The specific activity of 137Cs did not exceed the permissible level: in mineral sorbents its amount reached (40±7) Bq/kg, in organic and complex sorbents – (24±4), and in feed additives – (29±8) Bq/kg. The maximum levels of 40K were (1429±83) Bq/ kg in minerals (radionite) and (2613±100) Bq/kg in organic substances (lignohumate). The levels of 226Ra and 232Th did not exceed (153±13) and (79±13) Bq/kg, respectively, and were higher in the mineral samples.

Using the methods of arc atomic emission spectrometry (AAES), atomic emission flame photometry (AEFP), atomic absorption spectrometry (AAS) and mass spectrometry (ICP-MS), the elemental composition of the aerial part of widely used in medical practice Alfredia cernua and Filipendula ulmaria, extracts and fractions obtained from them, is investigated. It was shown that not only biologically active substances, but also mineral elements are extracted by extractants, which may be due both to the formation of complexes with biologically active substances and affinity for extractants. Therefore, the elemental composition must be considered as an important component of plant extracts and medicinal products obtained from them. Simultaneously with biologically active substances in ethanol extracts there is an accumulation of not only biogenic, but also toxic elements, which degree of extraction is often higher. It increases even more during the transition from periodic to countercurrent extraction, which allows to obtain extracts with the highest yield of biologically active substances. Since the enriched extract is directly used to obtain the dosage form, a preliminary elemental analysis is necessary. Analytical control of the content of TM is also necessary when choosing the place of growth of plants raw materials, which are used to create medicinal herbal remedies.
