Acetylation at O-2 of arabinofuranose residues in feruloylated arabinoxylan from bamboo shoot cell-walls.
Hydrolysis of bamboo shoot cell-walls with Driselase (a fungal enzyme preparation) gave an arabinoxylan trisaccharide with ferulic and acetic acids as ester groups. The structure of this oligosaccharide was determined to be O-[2-O-acetyl-5-O-[E)-feruloyl)-alpha-L-arabinofuranosyl]-(1----3) -O-beta- D-xylopyranosyl-(1----4)-D-xylopyranose, on the basis of spectroscopy and methylation analysis.
