The hydrolytic examination of plant cellulose isolated by the method of Druce and Willcox

Abstract

The cellulose isolated by the method of Druce & Willcox (1949a) has been examined by a hydrolytic procedure. The results confirm the high ‘hexosan’ content of the residues.The recovery of ‘hexosan’ from ‘bran cellulose’ has been shown to be very low (58%), and it has been demonstrated that the presence of large amounts of phytic acid is not responsible for this. It is suggested that ‘bran cellulose’ contains components which do not yield reducing sugars on hydrolysis.
