ABSTRACT
A fructan named ALF was isolated from the roots of Arctium lappa L. The structure of ALF was identified by analyses of methylation, GC-MS, and both 1H and 13C NMR spectroscopy. The results obtained indicated that ALF, comprised of D-fructose and D-glucose in the molar ratio of 14:1, was an inulin-type fructan, which was confirmed by the composition of 14 fructose residues linked by β (2→1) glycosidic bond and 1 glucose residue linked by α (1→2) glycosidic bond at the end of linear straight sugar chain.
