Abstract: | The glucomannan isolated from holocellulose pulp of Akamatsu (Pinus densiflora Sieb. et Zucc.) as its triacetate was methylated and the following methylated sugars were obtained by hydrolysis: the 2,3,4,6-tetra-O-methyl ethers of d-glucose and d-mannose (I part) and the 2,3,6-tri-O-methyl ethers of d-mannose and d-glucose (34–37 parts). Periodate oxidation of the glueomannan showed that 1.00 mole of periodate was consumed per mole of hexose unit and 3 moles of formic acid liberated for every 33 hexose units. |
