摘要

A glucogalactan with molecular mass 36 kDa and glucose:galactose ratio of 1.0:1.54 was isolated from leaves of Ficus carica L. The structure of the glucogalactan was studied by chromic oxidation, methylation, and 13C NMR spectroscopy. The main chain of the GG-Fc glucogalactan macromolecule included mainly β-1,3-bonded galactopyranose residues, several of which had C-4 side branches. The glucose residues were 1→6, 1→4, and 1→3 bonded via glycoside bonds. Galactose and glucose residues were found on the unreduced terminuses.
