Title: Polymeric proanthocyanidins: Interflavanoid linkage isomerism in (epicatechin-4)-(epicatechin-4)-catechin procyanidins

Author: Hemingway, Richard W.; Foo, L. Yeap; Porter, L. J.;

Date: 1981

Source: Journal of the Chemical Society Chemical Communications 7(320-322

Publication Series: Miscellaneous Publication

Description: Procyanidin trimers have been isolated from a variety of plants,1-3 but their structures remain unresolved. We have now isolated three configurational isomers of (epicatechin-4)-(epicatechin-4)-catechin from Pinus taeda L. (loblolly pine) phloem which exhibit isomerism of the interflavanoid linkages.
