AbstractCiders contain a series of procyanidins up to at least a seven‐fold degree of polymerisation, and a procyanidin tetramer based on epicatechin has been isolated by counter‐current distribution between ethyl acetate and water. Due to the shortcomings of modern methylation and mass spectrometry procedures molecular weights were determined by elevation of boiling point. Other techniques include a complex formation with dimethylaminocinnamaldehyde, and silica (h.p.t.l.c.) in toluene‐acetone‐formic acid mixtures.
