Abstract
Freeze-dried materials of cider apple pulp and skin were submitted to three successive solid-liquid extractions. The water-acetone extracts contained significant amounts of condensed tannins; thioacidolysis rev ealed that they were a mixture of highly polymerized procyanidins main ly constituted of (-)-epicatechin units. Electrospray ionization mass spectrometry showed a complete series of polymeric procyanidins with a degree of polymerization up to 17. Copyright (C) 1996 Elsevier Scienc e Ltd
