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 1 H and 13 C NMR spectroscopy. The results obtained indicated that ALF, com- prised 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 � (2�1) glycosidic bond and 1 glucose residue linked by � (1�2) glycosi- dic bond at the end of linear straight sugar chain.
