Chemical examination of the leaves of Pithecellobium lobatum has led to the isolation and characterization of five flavan-3-ol derivatives including new flavan-3-ol gallates, gallocatechin 3′- and 4′-O-gallates and gallocatechin 7,3′- and 7,4′-di-O-gallates (almost racemic), which occur as equilibrium mixtures. Examination of the pods afforded three proanthocyanidins (procyanidins B-3 and B-4 and prodelphinidin B-1), together with flavan-3-ols.
