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 (300×6.5 mm), and isocratic elution mode. &lt;strong&gt;Results&lt;/strong&gt;: Polysaccharide complex was isolated, the total content of polysaccharides in the rhizomes of &lt;em&gt;I. pseudacorus&lt;/em&gt; 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. &lt;strong&gt;Conclusion:&lt;/strong&gt; In our experiment polysaccharide complex was first identified and described in detail for &lt;em&gt;I. pseudacorus&lt;/em&gt; grown in Moscow region.&lt;/p&gt;
