Abstract:

Four evaluation methods of antioxidants in vitro such as prussian blue spectrophotometry measure, 1,10- phenanthroline-Fe2+ oxidative assay, riboflavin photodegradation-NBT reduction method and DPPH· method were used to evaluate the antioxidant activities of distilled water, 80% ethanol and ethyl acetate extracts of 27 plant samples. The results showed that all the extracts has strong antioxidant activity. However, their antioxidant activities show significant discrepancy, having close relations with extraction solvent, plant sample cultivars and activity assay methods.

Key words: edible and medicinal plant, antioxidant activity, radical scavenging
