An oligo-saccharide(CF-1) was purified from commercial enzyme(Alcalase, Novozyme) extract of Capsosiphon fulvescens by UF membrane system(sartorius, MWCO 2000). The oligosaccharide had an average molecular weight about 900 Da. It was composed mainly of glucose(96 %) and mannose(4%). Structural features of oligo-saccharide(CF-1) were elucidated by a combination of chemical and instrumental techniques, including FT-IR, GC-MS, 1H-NMR and 13C-NMR. The results indicated that CF-1 is a mannoglucan and has a backbone consisting of (1→3)-linked β-D-Glcp, 1-linked β-D-Manp.
