Additionally,
other correlations were established using SAR to explain the antioxidant behavior of the compounds with
unrelated groups: OH(C20

) > C2 = C3 + 4-oxo > OH(C3,C5) + 4-oxo > OH(C3)
+ 4-oxo > OH(C5) + 4-oxo > OH(C3,C5). Therefore, the use of these two tools together is very important
for the study of the antioxidant behavior of flavonoids, contributing uniquely to the understanding of
electronic transfer mechanisms involved in the antioxidant processes.
