摘要：

A water soluble 1,4-linked beta-D-glucan isolated from yellow mustard mucilage was characterized by one- and two-dimensional NMR spectroscopy. The complete assignment of the H-1 and C-13 resonances was obtained with the assistance of a heteronuclear shift correlated experiment. The connectivities within the residue were established through homonuclear correlation (COSY) while NOE correlation confirmed the 1,4-linked backbone chain structure. In addition, O-ethyl and O-propyl groups were found linked at C2, C3 and C6 positions in some of the glucosyl residues along the cellulose-like backbone chain.
