Summary
1. The partial hydrolysis of the polysaccharide of the leaves ofPlantago major L. has given degraded pectic acid.
2. A study of the physicochemical properties and IR spectra of the polygalacturonide and the products of its periodate-nitric acid oxidation has shown that the galacturonic acid residues in degraded pectic acid are in the pyranose from and are linked by a-0-1-4 bonds.
