The changes in antioxidant potentials were studied in Mentha piperita Linn. Plants under treatments with Gibberilic acid (GA), Abscisic acid (ABA) and Difenoconozole (DIZ) . The treatments were given as soil drenching methods on 30, 45, 60 and 75 days after planting (DAP). The plants were uprooted on45,60,75 and 90 DAP and separated into root, stem and leaf used for analyses. The antioxidant potentials potentials was studied in terms of non –enzymaticantioxidant molecules like ascorbic acid (AA), total phenol and reduced glutathione (GSH) and activities of antioxidant enzyme, viz., Peroxidase(POX), Superoxide dismutase (SOD), Ascorbate peroxidase(APX), Polyphenol oxidase (PPO) and Catalase (CAT). The GA ABA & DIZ treatments increased the AA, total phenol, GSH, APX, SOD, PPO, CAT. These preliminary results suggest that ,the application of GA,ABA &DIZ may be a useful tool to increase the antioxidant production in medicinal plants like M.Piperita.
