Fructans from Codonopsis pilosula Roots

The present study reports the presence of a β -D-fructopyranosyl-(2→1)-linked fructan in nature for the first time, with a β -D-fructofuranosyl-(2→1)-linked fructan in a mixture from Codonopsis pilosula . High-performance gel permeation chromatography (HPGPC) shows that the molecule weights of these two fructans are 2.33 and 1.31 kDa. Their structures were analyzed by 1D and 2D NMR.
