The present invention relates generally to catechin and epicatechin conjugates of formula (I). For example, a chemical synthesis process for the preparation of catechin and epi-catechin compounds, in particular of catechin and epi-catechin conjugates is disclosed. A further aspect of the invention pertains to new catechin and epi-catechin conjugate compounds.
for which sufficient amounts of them are required that cannot be obtained by isolation from biological fluids. This paper describes the preparation of the methyl, sulfate, and glucuronide derivatives of catechins using different chemical syntheses and their characterization by HPLC−DAD−ESI/MS. MS2 fragmentation of the compounds was also described that allowed the determination of the location of the different
