The article presents the survey data of 1830 average samples of feed, feed raw materials and food products received through the Test Center of the FSBSI «FCTRBS-RRVI»", provided by livestock and feed enterprises, agricultural companies, food manufacturers and 152 samples of feed provided by specialists of veterinary services , livestock enterprises, owners of peasant farms to determine the death of animals and birds, for the content of mycotoxin deoxynivalenol (DON) in the period from 2018 to 2020. Determination of the DON content in the samples was carried out according to a certified procedure based on the method of thin layer chromatography. In the course of summarizing the results, it was found that samples of feed, feed raw materials and food products received through the Test Center of the of the FSBSI «FCTRBS-RRVI» from different regions of the Russian Federation in terms of DON content corresponded to the normative indicators specified in the current regulatory and technical documentation. When determining the cause of death of animals and birds, 152 samples were examined, received from farms of different regions of the Republics of Tatarstan, Bashkortostan, Mordovia, Kostroma and Ryazan regions. It was found that 1.97% of samples were contaminated with DON at concentrations from 0.2 to 0.5 mg/kg of feed, in the rest, the content of mycotoxin was below the sensitivity of the method (< 0.2 mg/kg), which does not exceed the limit permissible concentration. It was recommended to exclude feed contaminated with mycotoxin from the diet of animals, since at the established concentrations, DON is not the main etiological factor in the death of animals, but due to the presence of carcinogenic, mutagenic, teratogenic, embryotoxic and immunosuppressive properties, together with other factors, it is contributing.

Introduction. Medicinal plant raw materials are one of the most important sources of herbal remedies used both for the prevention and treatment of a number of diseases [1, 2]. Even with the development of modern science and chemistry, medicinal plant raw materials are widely used in both folk and official medicine. The advantage of medicinal plants is their wide range of biological activity, low toxicity and the possibility of long-term use without significant side effects. Human economic activity has a noticeable negative effect on the condition of wild-growing plants: their stocks are decreasing, and some species disappear altogether. Today, given the high level of development of industry and agriculture, the procurement of raw materials for wild medicinal plants is not always possible. Information on the quantitative assessment of the raw material base of wild medicinal plants in the Middle Urals, the content of biologically active substances in medicinal plant raw materials is partially outdated, which determines the need for their systemic resource study and chemical-pharmacognostic study.Aim. Comprehensive assessment of the state of populations of wild medicinal plants in the Middle Urals.Materials and methods. Determination of stocks of raw materials of the studied species of medicinal plants was carried out on specific thickets according to the generally accepted method. The authenticity of the raw materials was established by a macroscopic method when collecting raw material samples. In the course of the study, samples of medicinal plant materials of 5 types were prepared. The determination and assessment of the main indicators of the good quality of medicinal plant raw materials (the content of active and extractive substances, moisture in the mass upon drying, total ash and ash insoluble in a 10% solution of hydrochloric acid) was carried out according to the methods and requirements of the State Pharmacopoeia of the Russian Federation XIV edition. In the raw materials Artemisiae absinthii herba and Leonuri herba, the amount of extractives was determined by the gravimetric method. The quantitative assessment of the content of essential oil in the samples of Origani vulgaris herba and Tanaceti vulgaris flores was carried out by the method of hydrodistillation. To determine the quantitative content of the sum of flavonoids in Hyperici herba, Artemisiae absinthii herba, Leonuri herba and the sum of flavonoids and phenolcarboxylic acids in Tanaceti vulgaris flores, a spectrophotometric method was used.Results and discussion. In the course of resource and phytochemical studies of representatives of the medicinal flora of the Middle Urals, a comprehensive assessment of the state of populations of wild medicinal plants – sources of medicinal plant raw materials (Origani vulgaris herba, Hyperici herba, Tanaceti vulgaris flores, Artemisiae absinthii herba and Leonuri herba) was carried out. The results are included in the electronic inventory of wild medicinal plants of the Middle Urals.Conclusion. The conducted complex of studies will allow updating information about the medicinal flora of the Middle Urals in order to use raw materials for the creation of medicines.

The flowers and fruits of various species of the hawthorn genus (Crataegus L.) are widely used in domestic and foreign medical practice as cardiotonic preparations. In our opinion, Crataegus submolls Sarg. is a perspective species for collection of the raw materials. Crataegus submolls Sarg. is successfully cultivated in the Russian Federation and is distinguished by its rapid growth and high yield compared with wild-growing species. Moreover, the fresh fruits of Crataegus submolls Sarg. are used in nutrition. The flowers of Crataegus submollis Sarg. contain flavonoids, among of which, like in the case of Hawthorn blood-red the hyperoside is present. It was determined that the maximum of the absorption curve of the solution of Crataegus submollis Sarg. flowers with a solution of aluminum chloride is 412 nm. The method of quantitative determination by the differential spectrophotometry of the total flavonoids calculated on hyperoside in the Crataegus submollis Sarg. flowers has been developed. It was established that the appropriate extragent for this raw material is 70% ethanol. The level of total flavonoid in Crataegus submollis Sarg. flowers has been studied. It was established that separate parts of Crataegus submollis Sarg. flowers differ markedly in the content of total flavonoids and their specific weight in raw materials. It was established that the content of total flavonoids calculated on hyperoside is varied from 2.05±0.08% tо 3.00±0.12%. It was determined that the content of total flavonoids calculated on hyperoside in different parts of hawthorn flowers ranges from 0.98% (receptacle and calyx) to 4.53% (petals).
