Abstract
Pavetannin A-2, a new A-type proanthocyanidin, along with the trimers cinnamtannin B-1, pavetannin B-1, B-2, B-3, B-5 and B-6 have been isolated in their free phenolic form from the stem bark of Pavetta owariensis. Spectral data and partial acid-catalysed degradation established their structures as ent-epicatechin-(4-alpha --> 8,2-alpha --> O --> 7)-catechin, epicatechin-(4-beta --> 8,2-beta --> O --> 7)-epicatechin-(4-alpha --> 8)-epicatechin, epicatechin-(4-beta --> 8,2-beta --> O --> 7)-epicatechin-(4-beta --> 8)-ent-epicatechin, epicatechin-(4-beta --> 8,2-beta --> O --> 7)-epicatechin-(4-beta --> 8)-epicatechin, epicatechin-(4-beta --> 6,2-beta --> O --> 7)-epicatechin-(4-beta --> 8)-epicatechin, epicatechin-(4-beta --> 6,2-beta --> O --> 7)-catechin-(4-beta --> 8)-epicatechin, epicatechin-(4-beta --> 8,2-beta --> O --> 7)-epicatechin-(4-alpha --> 8)-catechin, respectively.
