Journal of the Chemical Society C: Organic Pub Date : , DOI:10.1039/J39690001824
Abstract
The isolation of (+)-catechin 3-gallate and a polymeric proanthocyanidin from Bergenia crassifolia and B. cordifolia is described. Some properties of the polymer are discussed and a biosynthetic pathway for its formation is proposed.
