Abstract

Total phenolic content (TPC) and antioxidant activity of 7 coloured Capsicum genotypes in four different maturity stages were investigated. The total phenolic content of the genotypes determined by the Folin-Ciocalteau method was in average higher in the early phenophases than in the fully ripe phase. Among the genotypes the extreme lilac exhibited the highest amount of TPC as a result of the putative additive effect of the high levels of anthocyanins. On dry weight basis there was a 4.5-fold difference at the ripe stage in between the extreme lilac and the white berry genotypes. Antioxidant capacity of the samples during ripening followed a similar pattern than the TPC and the values showed positive correlation from green stage 2 onwards. The study indicates that anthocyanin pigmentation could add up to the functional properties of the peppers.
