• Lignins: Natural polymers from oxidative coupling of 4-hydroxyphenyl- propanoids (2004, background): “cofactor, H2O2, required for peroxidase-assisted oxidations (dehydrogenations), and possibly by radical quenching agents such as ascorbate (Christensen et al., 2000a; Sakihama et al., 2002).”
• Changes of phenolic metabolism and oxidative status in nitrogen-deficient Matricaria chamomilla plants (2007, background): “Phenoxyl radical raised from this H2O2 breaking to water can be regenerated by ascorbic acid (Yamasaki and Grace 1998); this is important step since phenoxyl radical can also initiate damage to biomolecules (Sakihama et al. 2002).”
• Physiological responses of Phaseolus vulgaris to different lead concentrations. (2010, background): “The antioxidant activity of phenolics is mainly due to their redox properties, which allow them to act as reducing agents, hydrogen donors, singlet oxygen quenchers and metal chelators (Sakihama et al., 2002).”
• ROS homeostasis in halophytes in the context of salinity stress tolerance. (2014, background): “Polyphenols are a group of water-soluble antioxidants with a superior ability to scavenge O2· , OH·, H2O2, and O2 compared with lipid-soluble carotenoids (Sakihama et al., 2002; Frary et al., 2010).”
• Sugarcane Under Pressure: An Overview of Biochemical and Physiological Studies of Abiotic Stress (2011, background): “In addition, for the detoxification of H2O2, phenolic compounds can act as antioxidants by donating electrons to guaiacol-type peroxidases, such as guaiacol peroxidase (GPOX) (Sakihama et al. 2002).”
• Effects of Cadmium on Phenolic Composition and Antioxidant Activities of Erica andevalensis (2012, background): “increase in the phenolic compounds was observed in T4 might be explained by taking into account that the phenoxyl radicals resulting from the antioxidative reaction could act as prooxidants [29].”
• Dietary Polyphenols and Their Biological Significance (2007, background): “Al, Zn, Ca, Mg and Cd have been found to stimulate phenoxyl radical-induced lipid peroxidation [185].”
• Phenolic compounds and their antioxidant activity in plants growing under heavy metal stress (2006, background): “It’s proper to mention that although the reduced forms of phenolic compounds act as antioxidants, the oxidized ones (phenoxyl radicals) may exert cytotoxic, pro-oxidant activity when the lifetime of the radicals is prolonged by effectors of spin-stabilization [55, 67].”
• Acquired tolerance of tomato (Lycopersicon esculentum cv. Micro‐Tom) plants to cadmium‐induced stress (2008, background): “In addition, for the detoxification of H2O2, phenolics can act as antioxidants by donating electrons to guaiacol-type peroxidases [guaiacol peroxidase (GPOX), EC 1.11.1.7] (Sakihama et al., 2002).”
