The 1H nmr spectroscopy provides a convenient method of assigning the orientation of the valoneoyl group in the oligomeric hydrolyzable tannins, which is the unit most frequently joining the monomeric constituents in the molecules. The behavior of oligomers upon partial degradation has been found to be dependent on the location of valoneoyl group on the glucose core.
