Hi,

To investigate the antioxidant activity of a plant extract i suggest you the following assays DPPH, ABTS, FRAP and the β-carotene bleaching assay to measure the relative antioxidant ability to scavenge the free radicals produced in the reagents.

Kind regards.

Two good researches give a good answer to your question and they are titled:

1.In vitro antioxidant activity and phenolic contents in methanol extracts from medicinal plants.

2. Antioxidant activity and phenol and flavonoid contents of eight medicinal plants from Western Nepal
