Over the years, a variety of assays to measure the total antioxidant capacity of pure substances, biological fluids, food extracts, and beverages have been developed. Among the most commonly used are the Trolox equivalent antioxidant capacity (TEAC), oxygen radical absorbance capacity (ORAC), and ferric reducing ability of plasma (FRAP) assays.

Due to the presence of different antioxidant compounds which may act through different meehanisms, no single method can be used to estimate the total antioxidant capacity of finits extracts. Different antioxidant assays were used to assess the antioxidant activity, such as ferric reducing ability of plasma (FRAP), permanganate reducing antioxidant capacity (PRAC), 2,2-diphenylpiciylhydrazyl (DPPH) ass, P-carotene bleaching assay, deoxyribose method.
