Tiivistelmä
A procyanidin dimer xyloside, catechin-(4 alpha -> 8)-7-O-beta-xylopyranosyl-catechin, was isolated from the inner bark of Betula pendula and its structure was determined using ID and 2D NMR, CD and high-resolution ESIMS. Interestingly, the 7-O-beta-xylopyranose unit was found to be present in the lower terminal unit of the dimer. In addition to this procyanidin dimer xyloside, an entire series of oligomeric and polymeric procyanidin xylosides was detected. Their structures were investigated by hydrophilic interaction HPLC-HRESIMS. Procyanidin glycosides are still rarely found in nature. (C) 2012 Elsevier Ltd. All rights reserved.
