Novel crystal modifications of (+)-catechin monohydrate and of (+)-catechin anhydrate more suitable for pharmaceutical preparations for reasons of higher stability against moisture and/or light and distinguished from hitherto known modifications by unique X-ray diffraction spectra are produced by specific recrystallization and/or crystal rearrangement processes and pharmaceutical preparations comprising the novel crystal forms.
