摘　　要：Three fructans (CoPS1, CoPS2 and CoPS3) vrere isolated from the root of Cyathula officinalis Kuan, a traditional Chinese medicine. The structures of the fructans were determined by methylation, reductive-cleavage method combined with GC-MS analysis, and 13C NMR spectroscopy. These results show that the fructans (CoPS1, CoPS2 and CoPS3) are graminan type fructans, and comprised of (2→1)- and (2→6)-linked β-D-fructofuranosyl backbone residues containing high branches.Three fructans (CoPS1, CoPS2 and CoPS3) vrere isolated from the root of Cyathula officinalis Kuan, a traditional Chinese medicine.
