Two dimeric proanthocyanidins have been isolated from the bark and roots of kenaf of variety Uzbekskii 1574. On the basis of chemical transformations and NMR and mass-spectral analyses it has been established that the proanthocyanidins have the structure of a dehydro dimer of 3,3′,4′,5,7-pentahydroxyflavan and that of 8-(3-galloyloxy-3′,4′,5,7-tetrahydroxyflavan-4-yl)-3,3′,4′,5,7-pentahydroxyflavan, respectively, with a C4-C8 (or C6) bond between the flavan moieties.
