摘要：

The structure and stereochemistry of a procyanidin glycoside, catechin 3-O-rhamnosyl-(4-alpha-->8)-catechin, obtained from Erythroxylum novogranatense have been established by chemical degradation and by means of spectroscopic methods of its peracetate. The preferred rotamer conformation of the peracetate was deduced from nuclear Overhauser effect difference spectroscopy and substantial chemical shift differences between the protons of the conformational isomers.
