The Existence of a Uronic Acid Ester in Young Wood of Eucalyptus regnans

Abstract

A comparison has been made between the hydrolysis of the hemicellulose in young Eucalyptus regnans F. v. M. and the hemicellulose in holocellulose prepared from the same wood sample. The rates of hydrolysis of the pentosan and uronic acid constituents have been compared. The results have been interpreted in terms of an ester in which uronic acid is thought to be involved.
