A chemical investigation of the leaves of Cornus officinalis has led to the isolation and characterization of a novel gallotannin, 1,7-di-O-galloyl-D-sedoheptulose, in addition to six galloylglucoses and five ellagitannins.The structure of the new compound was established on the basis of spectroscopic and chemical evidence.This is the first gallotannin possessing a heptose core.Key Word Index - Cornus officinalis; Cornaceae; 1,7-di-O-galloyl-D-sedoheptulose; D-sedoheptulose; gallotannin; tannin.
