摘要：

A polysaccharide, isolated from Centella asiatica, was a complicated arabinogalactan (AG), which contained a little alpha-(1-->4)-linked GalpA and alpha-(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 beta-(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.
