Abstract

P. G. Garratt, J. Hoigne, J. G. Heetman and W. Hess Holzforschung this work was obtained with amylose, where the total weight of the isolated free and combined glucuronic acid and its lactones was of the order of 1.6 per cent of the insoluble oxyamylose, and its apparent uronic acid content was 5.4 per cent (Stewart and Smelstorius 1968). As studies of wood polysaccharides are often based on chlorite holocellulose, the possibility has to be considered that the whole of D-glucuronic acid found may be an artifact, either due to oxidation of D-glucose moieties during chlorite holocellulose preparation or to demethylation of 4-O-methyl-D-glucuronic acid moieties during acid hydrolysis of the glucuronoxylan (Roudier and Gillet 1963). To minimize such a possibility the preparation of chlorite holocellulose should be carried out at temperatures lower than 75 °C as at present.
