Abstract

A fructan named ALF was isolated from Arctium lappa L. The structure of ALF was determined by methylation, GC-MS analysis, and both 1H and 13C NMR spectroscopy. These results showed that ALF is an inulin-type fructan that is comprised of D-fructose and D-glucose in the molar ratio of 14:1, which is 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.

 

Key words: Fructan, structure, Arctium lappa L.
