Partial hydrolysis of the mucilage of O. ficus-indica affords O-β-d-galactopyranosyl-(1→6)-d-galactose, the polymer-homologous trisaccharide, and fourteen oligosaccharides that contain arabinose and most of which have xylosyl end-groups. O-β-d-Xylopyranosyl-(1→5)-l-arabinofuranose and O-β-d-xylopyranosyl-(1→5)-O-α-l-arabinofuranosyl-(1→5)-l-arabinofuranose were the oligosaccharides isolated in greatest amount. The most-important structural features found in the peripheral chains in the mucilage are discussed.
