    Introduction. Vitamin preparations are widely used in the therapy of various diseases. The main dosage forms of the preparations include tinctures or decoctions. In addition to vitamins, medicinal plant raw materials, the components of the preparations, contain flavonoids. Objective: to develop methods for quantification of flavonoids in vitamin preparations. Material and methods. The investigation objects were model samples of vitamin preparations Nos. 1 and 2 and commercial samples of mountain ash (Sorbus aucuparia) berries, rose (Rōsa) hips, and black currants (Ribes nigrum). The amount of flavonoids was determined spectrophotometrically. Results. Optimal pH values and an optimal extractant for flavonoid-aluminum chloride complexation in the vitamin preparations were found to be 1.5-2.3 and 95% ethanol, respectively. It was ascertained that the amount of flavonoids in black currants and mountain ash berries should be calculated with reference to rutin and that in rose hips to luteolin. Conclusion. A spectrophotometric procedure was developed to determine the amount of flavonoids in vitamin preparations Nos. 1 and 2 and in their components: rose hips, mountain ash berries and black currants. Standardization of vitamin preparations Nos. 1 and 2 and their components was shown to be unreasonable in terms of the amount of flavonoids.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    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. HPLC-RID procedure was performed using Chromatograph Agilent 1260 Infinity, Sugar-Pak column (300Γ—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. Β© 2020 Phcogj.Com.

    This reviewcontains the analysis data on phytochemical composition ofthree-part beggarticks(Bidens tripartitaL.) and full biological activity spectrum of themedicinalraw material. Flavonoids, essentialoils, phenolcarboxylic acids, polysaccharides, aromatic hydroxy aldehydes, coumarins, tannins, and polyacetylenes are biologically active substances (BAS)ofB. tripartita.Various BAS cause multiple pharmacological and biological effects of theplant. Extracts possess antimycotic, antiinflammatory, antithrombotic, antiradical, antioxidant, antibacterial, antidiabetic, antiulcerogenic, and antitumor effects. The extracts are also ofanalgesic, antipyretic, antiallergic, hepatoprotective, immunostimulating,and hypotensive pharmacological effects. There is also a possibility to inhibit the main enzymes as well as to protect DNA. The B. tripartita medicinal raw material is of great importance for development and making of new drugs
