A method of synthesis of ‘dimers’ of catechin and epicatechin is described which gives 50% yields of the pure substances. The structures of the products are confirmed by nuclear magnetic resonance using 1 H and 13 C resonances and by mass spectrometry. Mass spectrometry using laser impact with (+) ions allows a rapid distinction to be made between the ‘dimers’ derived from catechin or epicatechin.
