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: 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.
