Stereochemistry and Oxidative Metabolism of Hydrolyzable Tannins

Abstract

Hydrolyzable tannins are a group of plant polyphenols consisting of a glucose core and acyl groups. Among them, ellagitannins have characteristic hexahydroxydiphenoyl and dehydrohexahydroxydiphenoyl groups as acyl groups. This review describes the chemical structures and stereochemistry of several hydrolyzable tannins, as well as their oxidative metabolism involved in ellagitannin biosynthesis.
