[2′,2′]-(+)-Catechin-(+)-taxifolin, a novel biflavonoid fromcommercialwillowbark (Salix spp.), is characterized by spectrometric methods. The bondingpositions are established by nuclear Overhauser effect difference spectroscopy of the methyl ether acetates of the bi-(+)-taxifolin analogues, which represent products of oxidation of the methylene function of the (+)-catechin moiety and which undergo
