  Two new oligomeric proanthocyanidin glycosides were isolated from trunk bark of Platanus orientalis. Their structures and relative configurations were found to be 7-O-β-D-Glcp-(–)-epicatechin-(4β-8)-(–)-epicatechin(4β-8)-(–)-epicatechin-3-O-gallate (platanoside-A) and 7-O-β-D-Glc $$ \textp}}\xrightarrow6} $$ galloyl-(+)-catechin-3-O-gallate(4α-8)-(–)-epicatechin-3-O-gallate-(4β-8)-(–)-epicatechin-3-O-gallate-(4β-8)-5-O-β-D-Glcp-(–)epicatechin-3-O-gallate (platanoside-B).
