Determination of hydrogen peroxide scavenging activity of cinnamic and benzoic acids employing a highly sensitive peroxyoxalate chemiluminescence-based assay: structure-activity relationships.
TLDR
Comparison between the two groups revealed that benzoate derivatives are much stronger hydrogen peroxide quenchers in relation with their cinnamate analogues, and this finding was discussed on a basis of structure-activity relationships and comparative assessment of other antioxidant characteristics.About:

p‐Coumaric acid and its conjugates: dietary sources, pharmacokinetic properties and biological activities
TL;DR: Cumulative evidence from multiple studies indicates that conjugation of p-coumaric acid greatly strengthens its biological activities; however, the high biological activity but low absorption of its conjugates remains a puzzle.

Plant Polyphenols as Antioxidant and Antibacterial Agents for Shelf-Life Extension of Meat and Meat Products: Classification, Structures, Sources, and Action Mechanisms
TL;DR: Commercially available polyphenols can decrease primary and secondary lipid peroxidation levels, inhibit lipoxygenase activity, improve meat color stability, minimize the degradation of salt-soluble myofibrillar protein and sulfhydryl groups, and retard bacterial growth.

Use of a Free Radical Method to Evaluate Antioxidant Activity
TL;DR: The antiradical properties of various antioxidants were determined using the free radical 2,2-Diphenyl-1-picrylhydrazyl (DPPH*) in its radical form as discussed by the authors.
Journal ArticleDOI
Methods for testing antioxidant activity
TL;DR: The measurement of antioxidant activities, especially of antioxidants that are mixtures, multifunctional or are acting in complex multiphase systems, cannot be evaluated satisfactorily by a simple antioxidant test without due regard to the many variables influencing the results.

Kinetics and Mechanisms of Antioxidant Activity using the DPPH.Free Radical Method
TL;DR: In this paper, the reaction mechanisms of three antioxidants are proposed in order to explain experimental results obtained from a kinetic study using the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, previously adapted in our laboratory.

Review: Methods Used to Evaluate the Free Radical Scavenging Activity in Foods and Biological Systems:
TL;DR: In this paper, the authors described the methods used for free radical scavenging in both substrates as well as in specific cases of their application, such as superoxide radicals scavenging (O2·-), hydrogen peroxide scavenging(H2O2), hypochlorous acid scavenging, HOCl, and hydroxyl radical scavenges (HO), among them, among them are the methods that use azo-compounds to generate peroxyl radicals.

Antioxidant properties of ferulic acid and its related compounds.
TL;DR: The results indicated that not only the radical scavenging activity of antioxidants, but also their affinity with lipid substrates, might be important factors in their activity.
