Xylosylpsicoses (XPs) were synthesized by transglycosylation (TG) with arabinoxylan (AX) and D-psicose (D-psi) using endo-1, 4-β-D-xylanase (EC 3.2.1.8) from Aspergillus sojae. The structures of XPs were analyzed by HPLC to determine sugar composition and molecular mass, by methylation analysis using GC-MS to determine linkage, and by ^1H- and ^<13>C-NMR spectrometries to obtain the anomeric configuration of glycosidic linkage. By chemical analysis, it was found that the structures of XPs are Xylpβ1-4P sip, Xylpβ1-5P sip, Xylpβ1-1P sif and Xylpβ1-6P sif.
