The article provides an overview of drugs based on buckthorn bark included in the State register of medicines of the Russian Federation and patented in recent years. The methods of quantitative determination of anthracenes-derived raw materials of buckthorn according to the state Pharmacopoeia of the Russian Federation XI and XIII editions and the European Pharmacopoeia are analyzed and presented in the comparative aspect. The main representatives of the anthracene-derived buckthorn are shown for a number of sources, taking into account modern phytochemical studies. The algorithm of development of a technique of spectrophotometric quantitative determination of anthracenes derivatives in buckthorn bark and extraction preparations from it is gradually presented. Studied and selected the optimal conditions of extraction: raw material grinding – 1 mm, extractant – 10% sodium hydroxide solution, the ratio of raw materials and extractant – 0.1 : 100, the extraction temperature in a water bath 100 °C, the duration of extraction – 30 minutes. The analytical maximum of 510 nm was established, a certified sample of frangul-emodin was used as a standard substance, and an experimental calculation of the specific absorption rate of frangul-emodin interaction products with an alkaline-ammonia mixture was presented. In the research we describe an optimized pharmacopoeial methodology, metrological characterizations and results of quantitative determination of the anthracene derivatives in aqueous and alcohol extracts based on the buckthorn bark. The content of the amount of anthracenes in the samples of raw materials of five domestic producers. The content varies from 4.35 to 4.85%.

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). In our opinion, Crataegus submollis Sarg. flowers are the promising type of medicinal plant raw materials.

The process of harmonisation of Russian and foreign approaches and requirements in the field of medicines quality assurance calls for revision of quality control procedures included in various regulations and guidelines. The monograph FS.2.5.0062.18 “Hawthorn flowers” of the State Pharmacopoeia of the Russian Federation XIV edition includes a test procedure for determination of flavonoids by a chromatospectrophotometric method. This procedure does not take into account current scientific capabilities and has a number of shortcomings, therefore it was necessary to revise the existing test procedure and develop a new approach to the standardisation of the hawthorn flower herbal substance.The objective of the study was to develop an assay method for standardisation and evaluation of hawthorn flower using high performance liquid chromatography (HPLC).Materials and methods: the study was performed using samples of hawthorn flowers by Russian manufacturers. Quercetin (USP RS) and Hyperoside (HWI, primary standard) were used as the reference standards. The HPLC analysis was performed using an Infinity II 1260 DAD LC system (Agilent), and the UV spectra were recorded on a Cary 100 Varian spectrophotometer. A TLC Visualizer (CAMAG) was used to obtain digital images of thin layer chromatography plates.Results: the authors developed an HPLC test procedure for quantitative determination of total flavonoids, expressed as hyperoside, in hawthorn flowers. The developed procedure gives reliable and reproducible results and is characterised by high sensitivity and selectivity. The results of quantitative determination of the total flavonoid content in hawthorn flowers were used to propose the standard for the total content of flavonoids, expressed as hyperoside, of “not less than 0.5%”.Conclusions: the developed assay method for determination of active pharmaceutical ingredients in hawthorn flower products by HPLC can be recommended for inclusion into the Assay part of the “Hawthorn Flowers” monograph of the State Pharmacopoeia of the Russian Federation.

The increasing demand for zinc and a range of zinc-related metals (for example: lead; indium; tin; cadmium; and copper) in the Russian Federation cannot be satisfied by the existing production plants due to the lack of raw materials. At the same time, ferrous and non-ferrous metallurgy and the chemical industry have accumulated hundreds of millions of tons of zinc wastes (falling into the hazard categories 2 to 4), the processing of which could not only make up the raw material base, but also improve the environmental situation. In the world, over 85% of ferrous dust is recycled using the Waelz process. The Waeltz process is used for distilling separation of elements under reducing conditions. In this study, a block diagram for production of the following elements from industrial wastes is proposed: zinc, cadmium and indium in form of massive metals; zinc and indium in the form of fine powders; and clinker as a raw material for cement production. The technical and scientific details of this new process have been patented in the Russian Federation and abroad. For the first time, the following operations have been implemented with the use of large-sized Waelz kilns: vapour-oxidized Waeltz treatment of polymetallic wastes; recycling of heat from gases and solid products with generation of process fumes; and implementation of alternative flux (dolomite) and alternative fuel (petroleum coke). Keywords: Waelz process, industrial wastes, heat recycling, vapour-oxidized Waelz processing

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.

The objects of the study were Mature dried fruits of Chinese birch (Lycium chinense Mill., this. Solanaceae (Solanaceae)). Four samples were examined: No. 1 (Gifts of Pamir, Russia), No. 2 (Gullin Tianhe Pharmaceutical, China), No. 3 (A. J. Alliance, Russia), No. 4 (Globaltorg, Russia). The purpose of this work is to determine the amount of carotenoids in the fruits of Chinese by spectrophotometry. The quantitative determination of the amount of carotenoids in the raw material of Chinese Dereza was carried out. Thin-layer chromatography was used to confirm the presence of carotenoids in the fruits of Dereza. The expediency of using the spectrophotometric method for the detection and quantitative determination of carotenoids in extracts from the fruits of Chinese birch is substantiated. The electron spectra of hexane, acetone and acetone-hexane solutions in the wavelength range 400–500 nm have a maximum optical density at 450±2 nm, characteristic of β-carotene. The optimal conditions of extraction of carotenoids from the raw materials of this plant (extractant – hexane; ratio "raw material–extractant" – 1 : 5; extraction time – 90 minutes; the degree of grinding of raw materials – 0.5 mm). It was determined that the error of a single determination of the content of carotenoids in the fruits of Chinese Dereza with a confidence probability of 95% is ±3,49%. It was revealed that the content of carotenoids in the raw material of Chinese Dereza varies in the range of 33–39 mg%.
