Applying an activity-guided fractionation, the naturally occurring key-antioxidants in beer were located and their structure elucidated. The development of a suitable quantitation technique revealed the compounds with a crucial impact on the antioxidant activity before confirming their influence on oxygen-mediated ageing reactions. For phenolic constituents newly discovered in beer, precursors were identified in barley as well as reaction pathways were revealed and the evolution throughout the brewing was ascertained.
