claimPolyphenolic compounds demonstrate structure–activity correlations where the placement of hydroxyl groups and conjugation patterns dictate radical scavenging efficacy.

claimThe dual anti-inflammatory and antioxidant activity of secondary metabolites from medicinal plants is due to chemical structures that facilitate direct radical scavenging and indirect regulation of cellular signaling.

procedureThe procedure for radical scavenging by polyphenolic compounds entails electron donation to neutralize free radicals, with the resultant phenoxyl radicals being stabilized via resonance structures.

claimPhytochemicals exert antioxidant effects through direct radical scavenging, metal chelation, and the upregulation of enzymatic antioxidant systems.
