Summary

1. The following monosaccharides have been found in the carbohydrate composition of readily hydrolyzable poly-saccharides of one-year willow wood: xylose, glucose, arabinose, galactose, and mannose, with xylose predominating.

2. The unhydrolyzable residues obtained from the hydrolysis of unbarked willow wood contain a large amount of carboxyl groups, from 0.62 to 1.00 meq/g.

3. The most promising willow species for use in the chemical wood-processing industry are those containing a large amount of polysaccharides including cellulose and the smallest amount of nonhydrolyzable residue:S. vitelina 66.46% of polysaccharides and 18.76% of nonhydrolyzable residue,S. urabensis 61.96 and 20.85%, respectively,S. superba 59.52 and 20.50%,S. viminalis gigantea 59.20 and 21.40%, andS. purpurea 58.44 and 23.30%.
