Resumo(s)
The ability of the aqueous extract of tronchuda cabbage (Brassica oleracea L. var. costata DC) external leaves to act as a
scavenger of DPPH- and reactive oxygen species (superoxide radical, hydroxyl radical and hypochlorous acid) was investigated.
A phytochemical study was also undertaken, and thirteen phenolic compounds and five organic acids were identified and quantified.
Tronchuda cabbage extracts exhibited antioxidant capacity in a concentration-dependent manner in all assays, although some
pro-oxidant effect was also noticed. The samples with higher phenolic and organic acid contents displayed the major antioxidant
potentials.
