Abstract: | A novel feruloylated xyloglucan disaccharide and p-coumaroylated arabinoxylan trisaccharide were isolated from cell walls of growing bamboo (Phyllostachys edulis) shoots. On the basis of chemical and spectral data, their structures were determined to be O-(4-O-trans-feruloyl-alpha-D- xylopyranosyl)-(1----6)-D-glucopyranose and O-5-O-(trans-p-coumaroyl)- alpha-L-arabinofuranosyl]-(1----3)-O-beta-D-xylopyranosyl-(1----4)-D- xylopyranose, respectively. This is the first reported evidence of a phenolic acid covalently associated with the cell wall hemicellulose, xyloglucan. |
