Abstract
Successive extraction of the bark with solvents of increasing polarity yielded about 60% of soluble material. The alcohol and water extracts contained principally simple polyphenols and their glycosides, tannins, mono-and disaccharides, soluble hemicelluloses and pectins. Hot water extracts are suitable for production of adhesives by reaction with formaldehyde, but their polyphenol content is only 50%. The polyphenols and their glycosides, and glucosides of hydroxystilbenes, were investigated in detail.
