Scven oligosaccharides have been isolated from the tuberous roots of Asparagus cochinchinensis MERR. Determination of components, periodate oxidation, methylation, and partial degradation studies provided the evidences that they are neo-kestose and the other six oligosaccharides which possess non-reducing linear structure made up of 2→1 linked β-D-fructofuranose residues having a neo-kestose unit on the end of the molecule.
