  • Title: Chemical and spectroscopic studies of Cercidium praecox gum exudate.
    Author: León de Pinto G, Martínez M, Rivas C.
    Journal: Carbohydr Res; 1994 Jul 04; 260(1):17-25. PubMed ID: 8062287.
    Abstract:
    The structure of the polysaccharide from Cercidium praecox (R&P) Harms gum exudate has been studied by Smith degradation, by sugar and methylation analyses, and by 13C NMR spectroscopy. The results showed a (1-->4)-xylan core. Some xylose residues are substituted at O-2 by alpha-D-glucuronic acid and 4-O-methyl-alpha-D-glucuronic acid residues. beta-D-Glucuronic acid is present, probably as terminal residues. The arabinose is present as alpha-L-furanose and beta-L-pyranose.
