Water-soluble polysaccharides and pectinic substances from seed pods of Crotalaria alata L. (Uzbekistan) and Crotalaria sp. (India) were studied. The water-soluble polysaccharides were found to dominate over pectinic substances. Galactomannan GM-SP with a Man:Gal ratio of 4.4:1 was isolated from Crotalaria sp. seed pods. Its main chain consisted of 1,4-β-bound polymannans with 1,6-α-bound galactopyranose side residues. Sulfated derivatives of galactomannan from C. alata were prepared. The supramolecular structures of the galactomannan and its sulfated derivative were studied using electron microscopy. The galactomannan sulfated derivative exhibited anticoagulant activity.
