Investigations of rhubarb and the bark of Rhaphiolepis umbellata led to the isolation of new flavan-3-ol glucosides.Their structures were elucidated on the basis of 1H and 13C NMR analysis and hydrolytic studies as (+)-catechin 5-O-β-D-glucopyranoside and (-)-catechin 7-O-β-D-glucopyranoside.Key Word Index - Rhubarb; Polygonaceae; Rhaphiolepis umbellata; Rosaceae; flavan-3-ol glucosides; catechin.
