Antioxidants: Classification, Natural Sources, Activity/Capacity

There is still no universal test for measuring total antioxidant capacity (TAC). There are many in vitro chemical tests that quantify the antioxidant scavenging activity of free radicals and their ability to chelate metals and that reduce free radical damage.

Analytical Methods Used in Determining Antioxidant Activity: A Review

Out of the tests based on the transfer of a hydrogen atom, the following were presented: the Oxygen Radical Absorption Capacity (ORAC) test, the Hydroxyl Radical Antioxidant Capacity (HORAC) test, the Total Peroxyl Radical Trapping Antioxidant Parameter (TRAP) test, and the Total Oxyradical Scavenging Capacity (TOSC) test.

Antioxidant Activity/Capacity Measurement. 1. Classification

Because there is no widely adopted ¡°total antioxidant parameter¡± as a nutritional index for labeling food and biological fluids, it is desirable to establish and standardize methods that can measure the total antioxidant capacity (TAC) level directly from plant-based food extracts and biological fluids.

Measurement of antioxidant activity

Sireerat and Schulte (2012) determined the antioxidant activity of tea infusions, fruit juices and vegetable extracts using an automated amperometric DPPH assay, in which antioxidant capacity measurements were achieved using DPPH radical as an amperometric redox indicator, with a pencil Pb working electrode, in conjunction with a Pt counter-electrode and Ag/AgCl reference electrode.

Measurement of antioxidant capacity using the biological antioxidant

Antioxidant capacity in metabolic syndrome (MetS) and its components. Reduced antioxidant capacity is defined as mean biological antioxidant potential (BAP) < 2,000 ¦Ìmol/L. The BAP levels were significantly lower than reference value in low high density lipoprotein (HDL), high triglyceride (TG), and presence of MetS groups.
