Arabinoxylan from <i>Cryptocarya wightiana </i>Bark

1287-1288A homogeneous arabinoxylan (Ara-Xyl in 1.05:1 ratio) has been obtained from the major water soluble fraction of Cryptocarya wightiana bark gum by employing gel filtration on Sephacryl S-400 and SE-HPLC techniques. Methylation of the pure polysaccharide followed by GLC-MS analysis reveales a highly substituted 1,4-linked xylan backbone
