ISOLATION AND IDENTIFICATION OF O-(5-O-FERULOYL-α-L-ARABINOFURANOSYL)-(1-3)-O-β-D-XYLOPYRANOSYL-(1-4)-D-XYLOPYRANOSE AS A COMPONENT OF Zea SHOOT CELL-WALLS

Article abstract of DOI:10.1016/0008-6215(85)85155-7

Zea shoot cell-walls were hydrolyzed with 30 mM oxalic acid followed by treatment with "Driselase" (a Basidiomycetes enzyme preparation) to obtain carbohydrate fragments containing ferulic acid.The structure of the major feruloyl compound was identified as O-(5-O-feruloyl-α-L-arabinofuranosyl)-(1-3)-O-β-D-xylopyranosyl-(1-4)-D-xylopyranose on the basis of (13)C-n.m.r., methylation analysis, and partial acid-hydrolysis, alkali hydrolysis, or esterase hydrolysis followed by analyses of the hydrolyzate.
