A novel polysaccharide was extracted from Sipunculus nudus (SNP). The molecular weight (MW) of SNP was determined to be 9223 Da by high-performance gel permeation chromatography analyses, and the structure of the SNP repeat units was determined to be →3,4-β-D-GlcpNAC (1→ and →4) -α-D-Glcp (1→ in the ratio of 151; →2) -α -D-Galp - (1→ as a side chain; and β-D-Galp-(1→ and α- D-Glcp - (1→ as end groups by GC-MS analysis and NMR assays. The effect of SNP on hepatoma HepG2-bearing mice was analysed to verify its potential in the clin
