The range of naturally occurring profisetinidins is extended by characterization of the first (–)-fisetinidol(–)-robinetinidol dimer and of a novel analogue based on the 3-O-galloyl ester of (+)-catechin. These metabolites are accompanied by (–)-fisetinidol-(4α,2′)-robinetin, (–)-fisetinidol-(4α,6)-(+)-taxifolin, and (–)-fisetinidol-(4α,6)- and (4β,6)-(+)-ampelopsins. The latter three compounds are representative of the first natural profisetinidins with dihydroflavonols as constituent units.
