A new water-soluble polysaccharide UPP was obtained from Ulva Pertusa and its structure was studied. The structural analysis results showed that UPP was composed of eight residues. The bone structure of UPP was →4)-β-D-Xylp-(1→4)-α-L-Rhap3S(1→3,4)-β-L-Arap(1→3)-α-L-Rhap(1→2,4)-α-L-Rhap(1→4)-α-D-Galp(1→ and there were two main branches. The branch structure at the 3-position of 1,3,4-β-L-Arap was →3,4)-β-L-Arap(1→4)-β-D-Glcp3Me(1→4)- β-D-GlcpA(1→ and the branch structure at 2-position of 1,2,4-α-L-Rhap was →4)-β-D-GlcpA(1→4)-β-
