Ugni molinae Turcz. is a native shrub of Chile, known for its edible berries and its leaves, which have been the focus of recent attention, as a good source of phenolic compounds to be used in cosmetics and food products. The aim of this study was to assess the differences in the phenolic composition and antioxidant capacity of the ethanolic extracts from the leaves of 10 genotypes of U. molinae,...
The antioxidant or pro-oxidant activity of some dietary phenolic compounds has been determined by their reducing activity over Fe3+ and Cu2+. The FRAP method has shown that phenolic acids exert a high reducing activity that give rise to a decrease in linoleic acid oxidation mediated by Fe3+, measured as TBARS. However, the reducing activity of phenolic compounds over Cu2+ leads to linoleic acid oxidation...
