A DIMERIC HYDROLYZABLE TANNIN, SANGUIIN H-6 FROM SANGUISORBA OFFICINALIS L.

Abstract

A new hydrolyzable tannin, sanguiin H-6, has been isolated from the underground parts of Sanguisorba officinalis L. (rosaceae), and on the basis of spectroscopic data and partial hydrolysis study has been shown to have a novel dimeric structure containing sanguiin H-2 and pedunculagin moieties.
