Abstract
A hypoglycaemic constituent, panaxan A, isolated from the roots of Panax ginseng, was revealed to be a glycan with molecular weight of ca. 14000. Spectroscopic and degradative studies demonstrated that panaxan A is mainly composed of α - 1 →; 6 linked D-glucopyranose residues having branching at the C-3 position, the ratio of terminals, branching positions and intermediate units being ca. 1:1:2.Keywords
