MYRICATIN, A GALLOYL FLAVANONOL SULFATE AND PRODELPHINIDIN GALLATES FROM MYRICA RUBRA

Article abstract of DOI:10.1016/S0031-9422(00)80097-7

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 of 1H AND 13C NMR spectra, and from hydrolytic studies.Key Word - Myrica rubra; Myricaceae; myricatin; galloyl flavanonol sulfate; prodelphinidin gallates; tannins.
