摘　　要：A polysaccharide, isolated from Centella asiatica, was a complicated arabinogalactan (AG), which contained a little a-(14)-linked GalpA and a-(12)-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 b-(13)-linked D-Galp residues, with heavily branched side chains. Araf residues were linked to O-3 of (13, 6)-linked Galp residues.

关 键 词：ARABINOGALACTAN POLYSACCHARIDE Centella asiatica structure.
