Abstract
Sarkar and co-workers1 claimed to have shown that jute α-cellulose does not contain any pentose; we showed2, however, that xylose and arabinose are present, and this was confirmed by Adams and Bishop3 by a different method. Recently, Mazumdar and Sarkar4 have suggested that there is an inherent defect in the formic acid method5 adopted by us for this purpose. As required by them, the chromatogram of α-cellulose prepared from different jute holocelluloses6 with 17.5 per cent sodium hydroxide is reproduced in Fig. 1 to show that α-cellulose contains xylose and arabinose.
