Quantity content of free monosaccharides and water-soluble polysaccharides in above-ground part of Lamium purpureum L. was determined . The samples were collected in different regions of the Russian Federation. Free monosaccharides content was from 3.4 to l0.4 %. The highest amount of monosaccharides was in the samples collected in Rostov Region (10.4 %). Water-soluble polysaccharides content did not depend on the geographical location and made from 3.0 to 3.7 %. Water-soluble polysaccharides and pectine matters were extracted and their monomeric composition was determined. The conlusion is that main monomers of water-soluble polysaccharides are glucose, galactose, arabinose, rhamnose, galacturonic and glucuronic acids. Total content of uronic acids in the composition of water-soluble polysaccharides varies from 6.9 to 9.1 % and it does from 20.3 to 21.8%.in the composition of pectin matters.
