Free radical scavenging behavior of ten exotic tropical fruits extracts
Food Research International, 2011•Elsevier
The antiradical capacity (radical scavenger capacity, RSC) of bacuri, cajá, camu-camu,
carnauba, gurguri, jabuticaba, jambolão, juçara, murta, black puçá and puçá were studied
using the 2, 2-diphenyl-1-picrylhydrazyl radical (DPPH•) assay. To determine their RSC, the
second-order rate constants (k2) for the oxidation of these extracts by DPPH• were
calculated. The values of k2 were compared to natural and synthetic antioxidants. The k2
values (L/molgs), in methanol at 25° C, were 69.52, 26.03, 22.20, 18.04, 17.23, 16.56, 15.60 …
