Background: The aim of the present study was to examine the composition and content of the polysaccharide complex and polysaccharide fractions from yellow iris (Iris pseudacorus L.) rhizomes growing in Russian Federation (Moscow region). Materials and Methods: Traditional pharmacognostic methods were used in the analysis of polysaccharides as biologically active substances. The total amount of polysaccharides was determined by a gravimetric procedure with alcohol precipitation. Fractions of polysaccharides were isolated by sequential changing of solvents. The content of monosaccharides was determined by the method of high-performance liquid chromatography with refractometric detection (HPLC-RID) after acid hydrolysis. HPLCRID procedure was performed using Chromatograph Agilent 1260 Infinity, Sugar-Pak column (300{\texttimes}6.5 mm), and isocratic elution mode. Results: Polysaccharide complex was isolated, the total content of polysaccharides in the rhizomes of I. pseudacorus was determined, as well as their distribution by fractions (water-soluble polysaccharides, pectic substances, hemicellulose A, hemicellulose B), the composition of individual sugars (glucose, xylose, galactose, mannose, rhamnose, arabinose) was determined for each fraction. Conclusion: In our experiment polysaccharide complex was first identified and described in detail for I. pseudacorus grown in Moscow region.

Background: In the Russian Federation, the viburnum fruits are used to obtain infusions and syrups as medications. This medicinal herbal raw material contains a large number of biologically active substances: vitamins, anthocyanins, proanthocyanidins, flavonoids, hydroxycinnamic acids, iridoids, carbohydrates, organic acids, lipids etc. The research aimed to study one of the biologically active substances group responsible for the formation of the organoleptic properties of aqueous extracts{\textendash}monomeric carbohydrate composition and content. Materials and methods: Dried viburnum (guelder-rose) fruits, an aqueous infusion based on it, and viburnum syrup of industrial manufacture (Russia) were purchased from the pharmacy and prepared for research. For HPLC analysis of monomeric sugars Agilent 1260 Series HPLC system equipped with autosampler/injector, four-channel gradient pump, column thermostat, refractive index detector), software (ChemStation Version B.01), column (Waters Sugar-Pack I, 10 μm, 300 {\texttimes} 6.5 mm) were used. Isocratic elution was performed using purified water (with the addition of Ca-EDTA 0.05 mg/ml) as the mobile phase, at a flow rate of 0.5 mL/min. The column was maintained at 80{\textdegree}C, the refractive index detector {\textendash} at 35{\textdegree}C. The injection volume was 10 μL, analysis time {\textendash} 20 min. Results: The main free carbohydrates of viburnum fruits and preparations based on them are glucose, fructose, and sucrose. The total content of simple sugars in the viburnum fruits is 28.393 {\textpm} 0.528\%, in the infusion {\textendash} 0.499 {\textpm} 0.015\%, in the syrup {\textendash} 69.736 {\textpm} 1.551\%. The characteristic ratio of glucose: fructose: sucrose in dried viburnum fruits is 8.1:5.4:1, in infusion {\textendash} 7.0:5.7:1, and in syrup {\textendash} 9.2:8.8:1. The sugars{\textquoteright} degree of passing into infusion is 74.34\%. Conclusion: The composition and content of carbohydrates determined by HPLC-RID are an important characteristic data. It can be used for viburnum fruits Russian pharmacopoeial standardization along with the quantifying total content of organic acids.

Background: Currently, the chemical composition of Laminaria J.V. Lamour. species is well studied; they have found applications in the food, cosmeceutical and pharmaceutical industries. The main groups of biologically active compounds are polysaccharides (alginic acid, laminarin, mannitol, fucoidan, and others) and minerals (iodine compounds, magnesium, potassium, calcium, iron) that are determined according to pharmacopoeial and All-Union State Standards requirements. Materials and Methods: For data obtaining various types of search tools and engines such as Google, Google scholar, scientific literature (including Russian sources), normative documentation of Russian Federation (State Pharmacopoeia of Russian Federation IV edition, All-Union State Standards, and others) electronic databases such as e-Library, Scopus, Web of Science, Pubmed were used. Results: In the course of this review study, a modern characteristic of the kelp thallus as a pharmaceutical, cosmeceutical, food substance of plant origin is presented. The data on the chemical composition, harvesting, and processing of raw materials are summarized. The standardization and safety issues of kelp thallus are considered taking into account modern pharmacopoeial and food international requirements. The approaches to the qualitative and quantitative analysis of biologically active compounds (polysaccharides, iodine) and the determination of safety indicators are studied. Conclusions: The regulatory documentation that is used in the quality control of kelp needs to be finalized and updated. For pharmacopoeial analysis, all possible physicochemical methods (gravimetric, titrimetric, spectrophotometric) should be presented in the newly approved monograph. In this case, modern procedures should be developed, including HPLC with various types of detection (determination of the carbohydrates profile and polysaccharides, including methods with acid and enzyme hydrolysis). This will ensure the required level of quality, the safety of kelp (Laminaria) raw materials.

Background: Today, there are some unresolved issues and discussions concerning inulin quantitative determination in medicinal plant raw materials (MPRM). MPRM containing polyfructans or fructosans (inulin and others) are rather complex multicomponent matrixes with many interacting compounds. The article discusses the prospects for further standardization of inulin-containing pharmacopoeial MPRM that include, in addition to polysaccharides (inulin), other biologically active compounds with pharmacological activity. Materials and Methods: Different types of search tools such as Google scholar, Google, scientific literature, normative documentation of Russian Federation (State Pharmacopoeia of Russian Federation IV edition and others) electronic databases such as e-Library, Scopus, Web of Science, Pubmed had been searched and data obtained. Results: The pharmacopoeial spectrophotometric procedures of inulin determination in the Russian Federation are approved in a version that does not fully satisfy modern standardization criteria. Regulatory changes required in the near future. Conclusion: Undoubtedly, to determine inulin quantitatively, it is necessary to modify the existing spectrophotometric procedures and introduce an additional alternative, more specific HPLC-RID (or similar) ones.

Background: Phytoadaptogens, biologically active compounds increasing the nonspecific resistance of the human organism, are well known for the prevention and correction of stressful conditions. Phytoadaptogens group includes phytoecdysteroids and polyphenols, that are characterized by the multiplicity of pharmacological effects in combination with the low toxicity. According to literature data, spinach (Spinacia oleracea L.) is a promising source of these compounds. This work aims to systematize data on the chemical composition of biologically active compounds of spinach, that determine its adaptogenic properties and concentration methods in the spinach processing for use in specialized foods and dietary supplements. Materials and Methods: Manifold electronic search engines, electronic databases, and libraries such as Google, Google scholar, Crossref, Indian Science Abstracts, Emerging Sources Citation Index, e-Library, Scopus, Web of Science, Pubmed, Chemical Abstracts, Index Copernicus, scientific literature had been searched and data obtained. Results: Botanical characteristics of spinach, main cultivation conditions, the latest data on the chemical composition of raw spinach material cultivars and extracts based on it are presented in this study. Schemes for the obtaining of products enriched with polyphenols and ecdysteroids are considered, and ways of proper purification are mentioned. Conclusion: It is recommended to introduce spinach into the diet of healthy people in order to increase the functional reserves of a person during periods of hypovitaminosis, overwork, intense physical exertion, and also to compensate for the adverse effects of external factors. Spinach extracts containing phytoecdysteroids (20-hydroxyecdysone) and polyphenols (flavonoids) can be used as a prophylactic to overcome the negative effects of stress, accelerate recovery after strong physical and mental stress, particularly for people with extreme occupations, athletes, and those who are engaged in hard physical labor.
