Two new oligomeric proanthocyanidin glycosides were isolated from trunk bark of Platanus orientalis. Their structures and relative configurations were found to be 7-O-beta-D-Glcp-(-)-epicatechin-(4 alpha-8)-(-)-epicatechin-(4 alpha-8)-(-)-epicatechin-3-O-gallate (platanoside-A) and 7-O-beta-D-Glcp-->6galloyl-(+)-catechin-3-O-gallate(4 alpha-8)-(-)-epicatechin-3-O-gallate-(4 alpha-8)-(-)-epicatechin-3-O-gallate-(4 alpha-8)-5-O-beta-D-Glcp-(-)epicatechin-3-O-gallate (platanoside-B).
