POLYSACCHARIDES FROM THE INFLORESCENCES OF Matricaria matricarioides

Article abstract of DOI:10.1007/BF00579136

Fractionation of the polysaccharide complex of the inflorescences of pineapple weed has given a galacturonan and a pectic acid.The structures of the galacturonan and pectic acid have been studied by the methods of enzymatic hydrolysis, periodate oxidation, and exhaustive methylation.It has been established that the galacturonan is a linear polysaccharide consisting of D-galacturonic acid residues in the pyranose form with α-1->4-bonds.The main polysaccharide chain of the pectic acid consists of D-galacturonic acid residues in the pyranose form, D-galactose, L-arabinose, and D-xylose residues are covalently bound to carbon atoms 2 or 3 of the main chain of the polysaccharide.
