Stereochemical Structure Determination of Caffeine Complexes with Galloylated and Non-galloylated Catechins
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.
