Characterization of Polymerized Polyphenols by Size-exclusion HPLC

Abstract

Various kinds of high-molecular-mass polyphenols such as condensed tannins, hydrolyzable tannins, and polymerized anthocyanins, were readily characterized by a new size-exclusion HPLC method. This rapid analytical method may also be useful for the profiling of molecular mass distribution of polyphenolic constituents in many kinds of food materials. © 2002 by Japan Society for Bioscience, Biotechnology, and Agrochemistry.
