An investigation of the bark of Myrica rubra has led to the isolation and characterization of myricatin (a galloyl flavanonol sulfate) and four new galloyl prodelphinidin dimers, together with gallic acid, (±)-gallocatechin and 3-O-galloyl-(-)-epicatechin. Evidence for the structures of these compounds was obtained from analyses of1H and13C NMR spectra, and from hydrolytic studies. © 1983.
