Summary

Groundnut shell hemicellulose A1 has been shown to contain residues of D-xylose and D-glucuronic acid. The methylated polysaccharide gave on hydrolysis 2, 3, 4-tri-O-methyl-D-xylose, 2, 3-di-methyl-D-xylose and 2-O-(2, 3, 4-tri-O-methyl-D-glucuronosyl)-3-O-methyl-D-xylose in the molar ratio of 1: 30: 1. A structure is proposed for the hemicellulose which has a straight chain of ca. 30, 1: 4-linked β-D-xylopyranose residues with D-glucuronic acid existing as a side chain through the C2 position of one of the xylose residues.
