A pectic polysaccharide named comaruman (CP) was extracted from the aerial part of Comarum palustre with 0.7% aqueous ammonium oxalate and subsequent precipitation with ethanol. Oral administration of comaruman (5-100 mg/kg) was found to reduce a paw edema observed 24 h after injection of 2%
The pectic polysaccharide named potamogetonan (PN) was obtained using extraction of the leaves and stems of the common pondweed Potamogeton natans L. by an aqueous ammonium oxalate. The purified potamogetonan PN-300 was obtained using membrane ultrafiltration of PN and proved to be pectin with a
A pectic polysaccharide was isolated from the rhizomes of Acorus calamus L. The main component of its carbohydrate chain was represented by residues of D-galacturonic acid (>85%). In addition, this polysaccharide contained residues of galactose, arabinose, xylose and rhamnose (<10%). Structural
