Flavanols from tea have been reported to accumulate in the cell nucleus in considerable concentrations. The nature of this phenomenon, which could provide novel approaches in understanding the well-known beneficial health effects of tea phenols, is investigated in this contribution. The interaction between epigallocatechin gallate (EGCG) from green tea and a selection of theaflavins from black ...

The antioxidant potential of commercial beverages against peroxyl radical was determined using the Total Oxyradical Scavenging Capacity (TOSC) assay. Peroxyl radicals generated from thermal homolysis of 2,2'-azobis-amidinopropane oxidize alpha-keto-gamma-methiolbutyric acid to ethylene, which is monitored by gas chromatography. The TOSC of each beverage is quantified from its ability to inhibit...
