| 摘 要： | Centella asiatica has been used as remedy for sodation, stabilization and against lepra, anabrosis1 in the oriental countries. The low-molecular-weight constituents in Centella asiatica have been investigated1. However, no polysaccharides have been reported. 1BI was the first polysaccharide isolated from C. asiatica, which had immunostimulating activity in vitro. In present study, we report the structural features of 1BI. Experimental Extraction, isolation and purification Dried C.…

| Abstract: | 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. |
