TLDR
The free radical scavenging activity of different fractions obtained from successive fractionation of the six methanol extracts with organic solvents of different polarities; petroleum ether, CHCl 3, EtOAc and n-BuOH; showed that, the EtO Ac and n -BuOH fractions have the high activity with SC 50− 3 fractions have weak activity at SC 50 ≥ 200 and 100μg/ml, respectively as discussed by the authors.About:

Structure-antioxidant activity relationships of flavonoids and phenolic acids
TL;DR: The factors underlying the influence of the different classes of polyphenols in enhancing their resistance to oxidation are discussed and support the contention that the partition coefficients of the flavonoids as well as their rates of reaction with the relevant radicals define the antioxidant activities in the lipophilic phase.
