Abstract
Glucofructans were isolated and purified from the endosperm of naked barley and their structural significances were discussed. Four unknown glucofructans (unknown 1~4) and the mixture of higher glucofructans were obtained. The results on methylated glucofructans showed that d-glucose unit in the glucofructans was present as the end group and main chain consisted of 1, 2-linked d-fructofuranose residues and that each glucofructan except unknown 1 had the branching structure comprising of 2, 6-linked d-fructofuranose residues.
