Purified hemicellulose isolated from a young bael (Aegle marmelos) tree with 2.5M sodium hydroxide contained D-xylose and 4-O-methyl-D-glucuronic acid in the molar ratio of 7.43:1; traces of glucose, galactose, rhamnose, and arabinose were also present.The linkages between the monosaccharide units were determined by methylation analysis of a hemicellulose fraction (II A) and carboxyl-reduced, hemicellulose II A, and the results were corroborated by those from periodate oxidation and Smith degradation.The anomeric configurations of the D-xylopyranosyl residues were determined by chromium(VI) trioxide oxidation of the acetylated, carboxyl-reduced hemicellulose, and the aldobiouronic acid obtained from graded hydrolysis was characterized.These experiments clearly revealed the structure of this hemicellulose.
