Introduction. Type 2 diabetes mellitus is currently considered one of the most common non-communicable diseases. For the prevention and concomitant treatment of this pathology, various herbal remedies are successfully used, such as, for example, blueberry shoots. The plant contains phenolic compounds (anthocyanins, flavonoids, phenolcarboxylic and organic acids), which have antioxidant and hypoglycemic effects, and also accumulates macro- and microelements (Ca, Mg, Zn, Mn), which in turn can affect the course of diabetes mellitus. Complexes of elements with phenolic biological active substances (BAS) can affect the formation of a pharmacological response or change its severity. Therefore, it is possible to put forward a hypothesis about the potentiation of the antidiabetic action of phenolic compounds when they exist in the form of mineral complexes.Aim. To carry out a comparative assessment of the antidiabetic activity of the mineral complex rutin with zinc in comparison with precursor substances and extraction from blueberry shoots to predict the effect of elements on the course of this pathology.Materials and methods. The objects of the study were an aqueous solution (C = 0.18 mg/ml) of a model complex of rutin with zinc with a molar ratio of components of 1 : 1 and blueberry shoots purchased from a pharmacy in St. Petersburg. According to the information on the packaging, the region of raw material procurement is Altai Territory, Barnaul, the period for harvesting blueberries is July 2020. The complex of rutin with zinc was obtained according to the method described in the literature from the pharmaceutical substance rutin (Rutin, batch 332, valid until 26.03.2023, Sichuan Guangsong Pharmaceutical Co., Ltd., China, FS 000569-060514) and an aqueous solution (С = 0.13 mg/ml) zinc chloride (Zinc chloride, batch 39/G 4, valid until 09.10.2021, Neva Reaktiv, Russia, STP TU COMP 1-533-2012). The optimal ratio of components 1 : 1 for the formation of a mineral complex was established by us earlier experimentally using the Job's method. The mass of zinc chloride, which must be added to the extraction, and the mass of the complex for the preparation of its aqueous solution were calculated on the basis of the quantitative content of biologically active substances in blueberry shoots and the molar ratio of the components involved in the formation of the complex compound determined by the spectral method. The quantitative content of the main groups of biologically active substances (flavonoids, hydroxycinnamic acids, organic acids) was determined spectrophotometrically on SF-2000 instrument (Russia) and titrimetrically using the methods presented in Russian Pharmacopoeia XIV FS.2.5.0093.18 and FS.2.5.0012.15. The antidiabetic effect of the complex of rutin with zinc was evaluated in comparison with an aqueous extract from the shoots of common blueberries (the ratio of raw materials: extractant – 1 : 80), an aqueous solution of zinc chloride (concentration – 0.36 mg/ml) and their mixture (ratio 1 : 1) on a model of dexamethasone-induced type 2 diabetes mellitus in laboratory animals. Determination of blood glucose concentration was carried out using a portable glucometer "AccuChek Active" (Roche Diabetes Care, Germany). The presence of glucosuria and ketonuria was established using Ketoglyuk-1 test strips (Biosensor AN, Russia). Statistical processing of the results was carried out using the Microsoft Excel program according to OFS.1.1.0013.15.Results and discussion. The results of the content of glucose and ketones in urine showed that in the process of modeling diabetes mellitus, glucosuria and ketonuria are characteristic for all groups of animals, which confirmed the formation of a pathological process in rats. A lower content of glucose and ketones in urine was found in a group of animals that received a complex of rutin with zinc (glucose concentration – less than 2.3 mmol/l, ketone concentration – less than 0.2 mmol/l). Measurement of the concentration of glucose in the blood showed that the complex of rutin with zinc has the most pronounced hypoglycemic effect, while the water extract from blueberry shoots and an aqueous solution of zinc chloride have a minimal antidiabetic effect (blood glucose is 6.9 mmol/l versus 8,1 mmol/l and 7.9 mmol/l, respectively).Conclusion. The study of the influence of elements in the composition of phenolic complexes on the course of diabetes mellitus showed that the introduction of minerals has a positive effect on the severity of the pharmacological effect, which can serve as confirmation of the hypothesis about the potentiation of the antidiabetic effect of phenolic compounds when they exist in the form of mineral complexes. Thus, the complex of rutin with zinc showed the maximum activity in comparison with the solution of zinc chloride, extraction from blueberry shoots and their mixture, which suggests that the form of existence of natural phenolic compounds in the composition of mineral complexes is optimal both from the point of view of accumulation and from the side manifestations of a pharmacological response. The results of the study create the preconditions for further study of the effect of various elements in combination with marker phenolic components of antidiabetic herbal preparations on the course of diabetes mellitus, and also make it possible to conclude that natural mineral complexes have a prophylactic effect against this pathology.

Low caloric diet is used in the complex treatment of patients with diabetes mellitus and obesity. However, the reduced caloric food can inadvertently lead to decreased intake of micronutrients. The main goal of the research was to assess the necessity and effectiveness of the vitamin-mineral complex in the treatment of type 2 diabetes with obesity. Methods: 80 females suffering from type 2 diabetes and obesity, ranging from 40 to 65 years old participated in the study. The total patients were divided into two groups, each containing 40 patients. All patients were given a personalized diet and 1000mg of metformin every day. The experimental group, besides that, received vitamin-mineral complex. The biochemical analysis of the blood, composition of the body, and the complaint on micronutrient deficiency were taken before the experiment and after 14 days of the therapy. Results: Supplementation of the vitamin-mineral complex was associated with higher blood serum levels of vitamins B6, B12, B9, C, D, potassium, calcium, magnesium and zinc, and lower levels of glucose. Clinical manifestations, associated with micronutrient deficiency, were significantly decreased in patients who were given vitamin-mineral complex. All these changes were valid both in relation to the initial level in the study group and to the indicators after treatment in the control group. Conclusion: Micronutrient supplements may be a very important part of the combined therapy of patients with diabetes mellitus and obesity.

The object of this research is the herb Adonis vernalis and hydroalcoholic extracts obtained on its basis. By the nature of the action, the drugs Adonis vernalis belong to the group of cardiac glycosides and occupy an intermediate place between strophanthin and digitalis. In official medicine, biologically active compounds of Adonis vernalis are included in drugs such as Cardiovalen, Adonis-bromine, Caridiolin and Cardiophyte. In the extemporal formulation, the extract is part of the Bechterew’s medicine. Until recently, scientists have made significant progress in studying the phytochemical and pharmacological action of the herb Adonis vernalis. However, one should not be limited to the use of Adonis vernalis only for stimulating cardiac activity, one should also consider the promising antioxidant effect of flavonoids and phenolic compounds that are contained in this medicinal plant. Also, studies of the extraction conditions of the herb Adonis vernalis are not described in the scientific literature. The study carried out the extraction of the grass Adonis vernalis by various methods (static and dynamic). The type of extract was chosen as the most rational, which provides the maximum yield of extractives (phenolic compounds and cardiac glycosides). For this, the optimal extraction conditions were selected, namely, the particle size, the type of extractant, the value of the hydromodule and the extraction method. Accordingly, the optimal particle diameter for maximum extraction of biologically active substances of the herb Adonis vernalis is 2.5 mm, the optimal extractant is 70 % ethyl alcohol, the ratio of raw materials: extractant is 1:10, the optimal extraction method is maceration with constant stirring. Phytochemical studies of the quantitative composition of the main groups of biologically active substances were carried out using calorimetric and spectrophotometric methods of analysis. As a result of the optimization of the process and its introduction into production on an industrial scale, the value added effect will be achieved. And also a high-quality product has been created that will compete with broad-spectrum drugs already existing on the market.

The use of minor biologically active components of food (flavonoids) as functional food ingredients for foods for special dietary uses is a promising trend in prevention and treatment of carbohydrate and lipid metabolism disorders resulting from the metabolic syndrome and type 2 diabetes mellitus. Unlike the in vitro studies that are conducted mainly on cell cultures, the results of clinical studies may be influenced by low bioavailability of polyphenols. This fact makes it impossible to reach the beneficial effects of polyphenols in some cases. Thus, the problem of polyphenol bioavailability enhancement is the main direction in producing highly effective specialized anti-diabetic food products. In this review, the interaction between proteins and polyphenolic compounds is discussed from the viewpoint of the potential to protect polyphenols against degradation in the digestive tract, to increase their stability and pharmacological activity compared to those of the conventional compositions. The problems of interactions between polyphenols and food proteins, digestive enzymes and cell transporters in the gastrointestinal tract have not been sufficiently covered in Russian academic publications. The studies focused on the mechanisms of interactions between polyphenols and proteins, considering the corresponding structural changes are of interest for predicting possible changes in their bioavailability. Polyphenol binding to proteins is influenced by the primary structure of a protein macromolecule, the spatial distribution of amino acid residues responsible for polyphenol binding, and some other parameters characterizing the conditions of interactions.

The article presents study results of the effect of humic nature biologically active additive «Humilid» on carbohydrate metabolism, namely on glucose, insulin and C-peptide in alloxan-induced diabetes mellitus in rats. The purpose of the experiment was to investigate how “Humilid” affects carbohydrate metabolism in rats; to study and analyze the effect of the humic nature biologically active substance «Humilid» on metabolic processes. In the work we used biochemical methods for studying the blood of experimental rats. Adult male white rats were taken for the experiment, from which four groups were formed. The experiment lasted three weeks, during which the animals from the first experimental group received daily in addition to the main feed an aqueous solution of feed additive «Humilid» at dose 5 mg / kg of body weight of the active substance, and had free access to water. Rats of the second and third groups were injected with alloxan as a single intraperitoneal injection. The rats of the third group additionally received an aqueous solution of feed additive «Humilid». It was identified that “Humilid” has an antioxidant activity, which may be one of the mechanisms of its antidiabetic action, as it is known that alloxan causes free radical damage to β-cells with weak antioxidant protection. The use of a biologically active feed additive of humic nature was found to have a hypoglycemic effect in both healthy animals as well as in rats with alloxan-induced diabetes mellitus. It was found that the use of “Humilid” in rats enhances energy processes in their bodies of experimental animals. There was a decrease in glucose content in rats from second group by 11.9% (P ≤ 0.001) compared with the control one. At the same time, the glucose content in animals from third and fourth groups was higher by 35.9% (P ≤ 0.001) and 20% (P ≤ 0.001) higher than in animals from the control one. The insulin concentration in the blood of rats from the second group was 7.4% higher (P ≤ 0.05) compared to the animals from first group. The concentration of C-peptide was within the reference values. The levels of insulin and C-peptide concentration in animals of the third and groups were lower by 47.8% (P ≤ 0.001) and 32.4% (P ≤ 0.001) and 55.5% (P ≤ 0.001) and 37.5% (P ≤ 0.001) in comparison with animals of first group. A pronounced hypoglycemic effect, which was due to an increase in the sensitivity of tissues to glucoregulatory hormones and an increase in the body’s tolerance to excessive intake of carbohydrates. The obtained results of the study indicate the regulatory effect of humic feed additive «Humilid» on key links in the regulation of carbohydrate metabolism, which is characterized by the decrease in blood glucose level due to activation of the synthesis and secretion of insulin and C-peptide.

Catalpa bignonioides Walt. (catalpa) the family Bignoniaceae – a tree, which originates from North America. Catalpa bark contains resins and tannins. Monoterpene glycosides were found in the leaf. Catalpa seeds contain up to 30% of eleostearic acid. Decoctions are made of the bark of the tree. They serve as a gastric agent and have an anthelmintic effect. Decoction of the bark exhibits bronchodilator action, is used in the complex treatment of cancer. The leaves are used to treat skin diseases. The infusion of fruits has anti-herpetic and hypoglycemic properties. The aim of the work is to investigate biologically active compounds of the leaves of catalpa bignini. The object of the study was the leaves of common catalpa harvested in the summer of 2018 in Sevastopol. Chemical identification reactions and methods of chromatographic analysis were used to determine the major groups of biologically active substances of the leaves of the catalpa (chromatographic paper Filtrak FN No. 4, Munktell, Czech Republic). Chromatography was performed in pre-selected solvent systems: n-butanol‒acetic acid‒water (BAW) (4:1:2) ‒ I direction and 15% acetic acid ‒ II direction. Identification reactions were performed with aqueous and aqueous-alcoholic extracts of catalpa leaves. The qualitative composition of the phenolic compounds was investigated by paper chromatography. The content of the sum of phenolic compounds, hydroxycyclic acids and flavonoids was determined by the spectrophotometric method. Based on the held reactions and chromatographic analysis, by the characteristic fluorescence in the filtered UV light before and after treatment with chromogenic reagents and the values of Rf in the raw material the presence of the following groups of biologically active substances were determined: flavonoids, phenol glycosides, hydroxycoric acids. According to the chromatographic analysis, at least 9 substances of phenolic nature have been detected in the alcohol-aqueous extracts. For the first time, the presence of the following groups of biologically active substances: hydroxycoric acids, phenologic glycosides, flavonoids was determined in the leaves of catalpa. Quantitative content of natural compounds in the leaves of common catalpa: the sum of phenolic compounds (4,76 ± 0,04%), of hydroxycoric acids (3,42 ± 0,02%), of flavonoids (1,88 ± 0,02%). The results of the study will be used in the development of the draft quality control methods for medicinal plant raw materials.
