Comparative Evaluation of Total Antioxidant Capacities of Plant Polyphenols

Abstract: Thirty-seven samples of naturally occurring phenolic compounds were evaluated using three common in vitro assays for total antioxidant activity (TAC) testing: the Trolox Equivalent Antioxidant Capacity (TEAC), the Ferric Reducing Antioxidant Potential (FRAP) and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, in addition to the Folin-Ciocalteu reagent reactivity (FCR). We found that antioxidant hierarchies depended on the choice of assay and applied ANOVA analyses to explore underlying struc… Show more

“…Numerous studies (100102) have established an association between the chemical structure of flavonoids and their antioxidant capacity. The trapping of free radicals by these molecules is associated with their structure: The most active flavonoids are those which contain 3′-4′ dihydroxy groups on the B cycle and/or a 3-OH group on the C cycle (103).…”

“…Na taką ich zdolność wskazują również bada nia innych autorów z wykorzystaniem liści miłorzębu [13,14,15,23,24], a także badania przeprowadzone na liściach innych roślin, w tym np. winorośli właściwej [25], aronii czarnej [26], akki sellowej [27], bielunia surmikwiatu [28] czy jeżyny euro pejskiej [29].…”

“…It has been suggested that the antioxidant function exerted by natural flavones is completely dependent on their reducibility, derived from specific phenolic hydroxyl groups in their molecular structure (32). Evidence from Yang et al (6) indicates that natural flavones from grape seed extract elevate the activities of CAT, SOD and GPx, and mitigate the H 2 O 2 insult to muscle cells, further suggesting that flavones serve an antioxidant role.…”
