Abstract
The hemicellulose isolated by direct alkaline extraction of the wood has been shown to be a 4-O-methyl-D-glucuronoxylan. Methylation data indicate a backbone of approximately 110 D-xylopyranose units linked by β, 1 → 4 bonds with single units of 4-O-methyl-D-glucuronic acid linked by α, 1 → 2 bonds. The proportion of acid units to xylose is approximately 1:7. 2,3-Di-O-methyl-D-lyxose was isolated as an artifact.
