Abstract

A novel dimeric hydrolyzable tannin, euphorbin E, was isolated from the leaves of Euphorbia hirta. Its structure (1), having two dehydrohexahydroxydiphenoyl groups, and a dehydroeuphorbinoyl group as a novel connecting unit between two polyaroylglucose cores, was determined based on spectral and chemical evidence.
