Abstract

New proanthocyanidin trimers (14 and 15) and tetramers (16 and 17) have been isolated from the whole body of Vaccinium vitis-idaea L. (Ericaceae). The structures of these proanthocyanidins were established by thiolytic degradation and by analyses of the proton and carbon-13 nuclear magnetic resonance spectra. In addition, the presence of (–)-epicatechin (1),(+)-catechin (2),(–)-epigallocatechin (3),(+)-gallocatechin (4), procyanidins B-1 (5), B-3(6), A-l (8) and A-2 (9), and cinnamtannins B₁(10), D₁ (11), B₂ (12) and D2 (13) in this plant was demonstrated.
