Veratraldehyde as a corrosion inhibitor for Zinc in different acid medium. Veratraldehyde was reduced by aryl-alcohol dehydrogenase to their corresponding alcohols, which was oxidized by aryl-alcohol oxidase, producing H2O2.
Proanthocyanidins exerts antiviral, hepatoprotective, cardioprotective, hypolipidemic, anti-osteoporosis, anti-inflammatory ,antioxidant and anti-apoptosis activities. Dietary proanthocyanidins inhibits photocarcinogenesis in mice through the inhibition of UVB-induced inflammation and mediators of inflammation in mouse skin. Proanthocyanidins form stable complexes with metal ions and with proteins and are good reducing agents, they may participate in the prevention of cancers, both of the digestive tract and inner organs, they may also protect LDLs against oxidation and inhibit platelet aggregation and therefore prevent cardiovascular diseases.
Apiin as a reducing agent, used in biological synthesis of silver and gold nanoparticles. Apiin has anti-inflammatory properties, it has inhibitory activity in-vitro on iNOS expression and nitrite production when added before LPS stimulation in the medium of J774.A1 cells.
