A simple but elegant electrochemical (cyclic voltammetric) device was developed to detect antioxidative property of various substances (pure compounds, extracts of spices etc.). It was employed to investigate the presence of antioxidants / antioxidative agents, in some common herbal and medicinal plant products, for example saffron, clove, herbal tea etc. The concentration of such substances showing antioxidative property was estimated and they were categorized as per the voltammetric responses of some known antioxidants. The effectiveness / relative effectiveness of the antioxidants / antioxidative agents was also investigated.
Key words: Antioxidants, superoxide, saffron, herbal tea, clove, cyclic voltammetry.
