Structural features of a water soluble gum polysaccharide from Murraya paniculata fruits

A water soluble gum polysaccharide was isolated from Murraya paniculata fruits. Hydrolytic experiments, methylation analysis, periodate oxidation studies and NMR data revealed that the polysaccharide was extensively branched and it consisted of 1,3-, and 1,3,6-linked β- d-galactopyranosyl units, ter...

Description
Summary:A water soluble gum polysaccharide was isolated from Murraya paniculata fruits. Hydrolytic experiments, methylation analysis, periodate oxidation studies and NMR data revealed that the polysaccharide was extensively branched and it consisted of 1,3-, and 1,3,6-linked β- d-galactopyranosyl units, terminal β- d-galactopyranosyl units and terminal α- d-glucopyranosyl 1,4-β- d-galactopyranosyl units. Small amounts of 4- O-methylglucuronic acid residues were also present.
