Structural Features of a Polysaccharide from Centella asiatica

Shanghai Institute of Materia Medica, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, Shanghai 200031

Received Date: 1 February 2004

A polysaccharide, isolated from Centella asiatica, was a complicated arabinogalactan (AG), which contained a little α-(1→4)-linked GalpA and α-(1→2)-linked Rhap residues. Based on composition and methylation analyses, partial acid hydrolysis, periodate oxidation, NMR, ESI-MS experiments, it was shown to have a backbone of β-(1→3)-linked D-Galp residues, with heavily branched side chains. Araf residues were linked to O-3 of (1→3, 6)-linked Galp residues.
