In a chemical investigation epicatechin, epigallocatechin, the procyanidins B-1, B-3 and B-4, and the prodelphinidins gallocatechin-(4alpha,8)-catechin, gallocatechin-(4alpha,8)-epicatechin and gallocatechin-(4alpha,8)-epigallocatechin have been isolated from the testa of faba beans and characterized by means of spectroscopic methods. Proanthocyanidin samples were compared for their trypsin inhibitory activity. The results suggest that the degree of polymerization, the number of phenolic hydroxyl groups and the 2,3-stereochemistry of the constituent units affect remarkably the strength of the inhibition.
