Significance of Ferric-reducing antioxidant power assay
The Ferric-reducing antioxidant power assay is a laboratory method used to evaluate the antioxidant capacity of various substances, including plant extracts and essential oils, by measuring their ability to reduce ferric ions to ferrous ions. This assay involves mixing samples with a ferric reagent and measuring absorbance, with results compared to standard antioxidants like ascorbic acid. It effectively indicates potential antioxidant properties through color changes in the solution, demonstrating the reducing power of both extracts and nanoparticles.
