Summary

The hemicelluloses of the tubers ofAsparagus racemosus Willd. have been isolated and chemically examined. Two fractions,viz., A2 and B2 of Norris and Preece designation, have been obtained.

Both the fractions are constituted from the same sugar and uronic acid, namely, glucose and galacturonic acid but in different proportions. In hemicellulose A2 the molecular ratio of these compounds is 10:1, while in B2 it is 5:2. Under conditions of partial hydrolysis, both the fractions give rise to glucose and a gluco-galacturonic acid.
