Linkage of phenolic acids to cell-wall polysaccharides of bamboo shoot.

Abstract

Hydrolysis of bamboo shoot cell walls with Driselase (a fungal enzyme preparation) gave xyloglucan and arabinoxylan oligosaccharides containing ferulic and p-coumaric acids, respectively. The structures of two oligosaccharides containing phenolic acids are here determined to be O-(4-O-trans-feruloyl-alpha-D-xylopyranosyl)-(1----6)-D-glucopy rano se and O-[5-O-(trans-p-coumaroyl(-alpha-L-arabinofuranosyl]-(1----3)-O-be ta-D-xylopyranosyl-(1----4)-D-xylopyranose, on the basis of n.m.r. spectroscopy, methylation analysis, and f.a.b.-m.s. The possible role of phenolic acid substituents in cell-wall architecture is discussed.
