Article abstract of DOI:10.1016/0031-9422(88)80042-6

An investigation of the root of Potentilla viscosa has led to the isolation and characterization of a novel 6',8-linked bisflavanoid, potentillanin and a procyanidin B-3,3'-O-glucoside.Furthermore, the occurrence of (+)-catechin and its 3-O-glucoside, procyanidins B-3 and C-2 and afzelechin-(4α->8)-catechin was demonstrated.Key Word Index - Potentilla viscosa; Roseceae; potentillanin; bisflavanoid; flavan-3-ol glycoside; procyanidin glycoside; proanthocyanidin.
