Summary Reversed-phase, high-performance liquid chromatography coupled to photodiode array detection has been used to analyse catechins and proanthocyanidins extracted from grape seeds. Results show that the ethyl acetate fraction obtained by passing extracts of samples adjusted to pH 7.0 through preconditioned C18 SEP-PAK cartridges contains several catechins and proanthocyanidins. Seven peaks have been assigned to standard catechins and proanthocyanidins on the basis of their retention times and UV spectra. Other peaks which appear in the chromatogram show spectral behaviour similar to that of standard catechins and proanthocyanidins.
