Stereochemical structure determination of caffeine complexes with galloylated and non-galloylated catechins

Takashi Ishizu, Takashi Sato, Hiroyuki Tsutsumi, and Hideji Yamamoto*

ABSTRACT: Stereochemical structures of a 1:1 complex of (-)-epicatechin (EC) and caffeine, and a 2:4 complex of (-)-epicatechin gallate (ECg) and caffeine were determined by X-ray crystallographic analysis, and noncovalent interactions forming between EC, ECg and caffeine moieties were also elucidate.
