We characterized polysaccharide complexes from
Centaurea scabiosa
L. and
Centaurea pseudomaculosа
Dobrocz. We proposed the technique of sequential selection of water-soluble polysaccharides and pectin substances from the aerial parts of studied objects. We have discovered that the content of water-soluble polysaccharides in the aerial parts of
C. scabiosa
was 2.8 times higher (2.7 ± 0.3%,
n
= 3) than in
C. pseudomaculosа
(0.97 ± 0.50%,
n
= 3). The content of pectin substances in the aerial parts of
C. scabiosa
was 2 times higher (7.6 ± 0.4%,
n
= 3) than in
C. pseudomaculosа
(3.9 ± 0.3%,
n
= 3). The residues of D-galacturonic acid, L-rhamnose, D-xylose, D-mannose, D-glucose, and D-galactose are the monomeric units of polysaccharide complexes from
C. scabiosa
and
C. pseudomaculosa
. Using ion-exchange chromatography, three polysaccharide fractions (molecular weights 667, 722, and 1027 kDa), whose monomer units are D-galacturonic acid, L-rhamnose, D-galactose, D-xylose, and D-glucose were isolated from the water-soluble polysaccharides of C. scabiosa.
