Sulfated xylomannans were isolated from two species of genus Chondrophycus by aqueous extraction followed by KCl fractionation. Structural determination of the native, desulfated and Smith-degraded KCl-precipitated polysaccharides carried out by composition and methylation analysis and NMR spectroscopy (1D and 2D experiments) showed the following general structure:Figure optionsDownload full-size imageDownload as PowerPoint slideThese xylomannans present different degrees of branching (15–25%) by β-d-Xylp (70–80%) and β-d-Manp-2-S (20–30%) and molecular weights (33–222 kDa). This is the first report of the presence of a sulfated xylomannan in species of order Ceramiales.
