[Analytical 1H-NMR-study of some natural Rotameric procyanidins].
The phenomenon of conformational isomers of naturally occuring dimeric B-procyanidins has been studied systematically by the 270 MHz- (1)H-NMR spectra of the acetate derivatives and the observed data are presented as an additional analytical criterion.
