Aim. The aim of the study was to develop the methodical approach to determine the antioxidant activity of the tinctures of Monarda fistulosa herb and flowers and roots of Echinacea purpurea, as well as to develop their technology in laboratory conditions.

Materials and Methods. The following methods were used: analysis, synthesis, systematization, and comparison for processing of published scientific data on antioxidant activity; method for measuring the particle size of raw herbal materials; maceration and remaceration methods for obtaining the tested tinctures; DPPH test for the valuation of the antioxidant activity of the developed tinctures.

Results and Discussion.

The methodical approach to determining the antioxidant activity of the tinctures of Monarda fistulosa herb and flowers and roots of Echinacea purpurea was elaborated, the essence of which consisted in the selection of the appropriate dilution of the tinctures. The six liquid tinctures were prepared with the help of maceration or/ and remaceration in laboratory conditions. The ratios of herbal raw materials (HRM) to the final tincture were close to ratios that are widely employed in the pharmaceutical industry, namely 1 to 5 and 1 to 10. The coefficients of alcohol absorption for the roots of Echinacea purpurea (size 2-5 mm), flowers of Echinacea purpurea (size 1-3 mm), herb of Monarda fistulosa (size 0.5-3 mm) were measured. They were measured as 1.2, 2.25, and 5.0 ml/g, respectively, for 70% ethanol. The studies revealed that Echinacea purpurea tinctures are a valuable source of antioxidant compounds. The antioxidant activity of these tinctures was 254.8-815.8 mg rutin-equivalents in 1 L of the tinctures or 1.12-4.43 mg rutin-equivalents in 1 g of the HRM depending on the part of the plant, particle size and extraction type. The antioxidant activity of the tinctures of the Monarda fistulosa herb was equal to 2203.6 mg eq-rutin/L and 20.3 mg eq-rutin/g for the tincture at a ratio of 1 to 9.5 and 2119.4 mg eq-rutin/L and 9.7 mg eq-rutin/g for the tincture at a ratio of 1 to 4.5.

Conclusions. The approach to the determination of the antioxidant activity of the tested tinctures was elaborated, namely the dilutions of the tinctures were established for the analytical procedure of the determination of the antioxidant activity. Our studies demonstrated that tinctures of Echinacea purpurea contained compounds with antioxidant activity. The tinctures of Monarda fistulosa herb are very rich in compounds with antioxidant properties. The laboratory technology of six tinctures was elaborated. Further studies will be directed at laboratory studies on microorganisms and animals

This review aims to analyze Mentha piperita L. as a potential raw material for the development of new health promoting products (nutraceuticals, cosmetics, and pharmaceutical products). A lot of scientific publications were retrieved from the Scopus, PubMed, and Google Scholar databases which enable the study and generalization of the extraction procedures, key biologically active compounds of essential oil and extracts, biological properties, and therapeutic potential of M. piperita, along with perspectives on the development of its dosage forms, including combinations of synthetic active substances and herbal preparations of M. piperita. The results of this review indicate that M. piperita is a source rich in phytoconstituents of different chemical nature and can be regarded as a source of active substances to enhance health and to develop medicinal products for complementary therapy of various conditions, especially those related with oxidant stress, inflammation, and moderate infections. Essential oil has a broad spectrum of activities. Depending on the test and concentration, this essential oil has both anti- and prooxidant properties. Gram-positive bacteria are more sensitive to the essential oil of M. piperita than Gram-negative ones. This review also considered some facets of the standardization of essential oil and extracts of M. piperita. Among the identified phenolics of extracts were caffeic acid, rosmarinic acid, eriocitrin, luteolin derivates (luteolin-7-O-rutinoside, luteolin-7-O-glucoronide), and hesperidin. The concentration of these phenolics depends on the solvent used. This review also considered the relationships between the chemical component and biological activity. The results showed that the essential oil and extracts reduced inflammation in vitro by inhibiting the production of pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6), and in vivo by reducing the paw edema induced using carrageenan injection in rats. Therefore, herbal preparations of M. piperita are promising medicinal and cosmetic preparations for their usage in skincare and oral cavity care products with antimicrobial, antiinflammatory, and wound-healing properties. This plant can also be regarded as a platform for the development of antibacterial preparations and combined anti-inflammatory and cardioprotective medicinal products (synthetic active substances plus herbal preparations). This review could be considered for the justification of the composition of some medicinal products during their pharmaceutical development for writing a registration dossier in the format of Common Technical Document.

The aim of this study was to assess the level of nitric oxide production and arginase activity in patients with arterial hypertension and type II diabetes mellitus during infection with SARS-CoV-2. The study groupsvincluded patients with arterial hypertension, patients with arterial hypertension combined with a severe course of COVID-19 and patients who, in addition to arterial hypertension and COVID-19, were suffering from type II diabetes mellitus. The volunteers without any clinical signs of diseases and normal blood pressure formed the control group. It has been established that arterial hypertension, combined with COVID-19 occurs along with reduced L-arginine, nitric oxide, superoxide dismutase activity and increased arginase activity. At the same time, the presence of arterial hypertension in patients with diabetes and coronavirus disease is accom-panied by a decline in the content of L-arginine and arginase activity. Our study’s results may help scientists find new pharmacological targets in the future treatment of coronavirus disease and comorbid disorders.
