Fructans from Codonopsis pilosula Roots

The present study reports the presence of a beta-D-fructopyranosyl-(2 -> 1)-linked fructan in nature for the first time, with a beta-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.
