Pavetannins C-2 to C-6, five new tetrameric proanthocyanidins containing one or two double interflavanoid (A-type) linkages have been isolated from the stem bark of Pavetta owariensis. Spectroscopic investigations and partial acid-catalysed degradation established their structure as epicatechin-(4β → 8,2β → O → 7)-ent-catechin-(4β → 8)-epicatechin-(4β → 8)-epicatechin, epicatechin-(4β → 8,2β → O → 7)-ent-epicatechin-(4α → 8)-ent-epicatechin-(4α → 8)-epicatechin, epiafzelechin-(4β → 8,2β → O → 7)-epicatechin-(4β → 8)-epicatechin-(4β → 8)-epicatechin, epiafzelechin-(4β → 8,2β → O → 7)-ent-afzelechin-(4α → 8)-ent-epicatechin-(4α → 8,2α → O → 7)-ent-catechin and epiafzelechin-(4β → 8,2β → O → 7)-ent-catechin-(4α → 8)-ent-epicatechin-(4α → 8,2β → O → 7)-ent- catechin, respectively. While aesculitannin F is being reported from a plant source for the second time, the remaining tetramers are new natural metabolites.
