-
Five pectic polysaccharides CPA-CPE were purified from the pollen of Codonopsis Pilosula [Franch] Nannf. They are all composed of L-arabinofuranosyl and D-galactopyranosyl residues. The results of methylation analysis and periodate oxidation and Smith degradation revealed that CPA was a highly branched arabinogalactan probably with a backbone of (1→6) D-Galp. Electron micrograph of CPA showed a secondary structural feature of a string of pearls.
