Abstract: | The structures of two polysaccharides reported in the previous paper were studied by means of methylation analysis and the Smith degradation. As a result, it was concluded that the water-soluble xylan consisted essentially of a (l→4)-linked β-d-xylopyranosyl chain and contained l-arabinofuranosyl residues linked through the C–l as terminal side units. Unambiguous information concerning the residues of d-glactose and d-glucuronic acid as the constituents of the xylan has not been obtained. For the arabinogalactan, evidence was obtained for an interesting structure having a backbone chain of (l→3)-linked β-d-galactopyranosyl residues to which the terminal arabinose residues were attached at the C–6 position as the most prevalent side chains. |
