Using a detailed HPLC–ESI-MS analysis including both high resolution and tandem MS analysis, a series of fourteen novel flavonoids were identi fied from alcoholic extracts of raw fermented cocoabeans from Cameroon. The novel compounds includea series ofisomerichexosides of flavan-3-ols and novel proanthocyanidine dimers and trimers and asulfated flavan -3ol. Additionally a jasmonic acid sulfate derivative was identified in the cocoa bean extracts as one of the major metabolites produced under fermentation stress.Therefore,thechosenHPLC–ESI-MS
analysis method revealed a greater complexity of the cocoa bean polyphenolic extract than previously reportedand allowed individual assignment of novel compounds.
