ABSTRACT

Antioxidants are the molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged. Although there are several enzyme systems within the body that scavenge free radicals. Fruits, vegetables, cereals etc. plays a vital role in scavenging the free radicals which are produced through various ways especially during metabolism. The present study is focused on the the ability of pulp and peel extracts of the fruit to quench the free radicals through several experimental models. These anti-radical powers was effectively measured by 1, 1-diphenyl-2- picryl-hydrazyl radical (DPPH) radical scavenging, ABTS radical scavenging, Reducing power, Nitric oxide radical scavenging, hydroxyl radical scavenging and metal chelating assays. The antioxidant activity of peel and pulp of different solvent systems exhibit an increase in concentration dependent manner and the reference used was BHT and TBA. The results obtained in the present study indicate that the peel and pulp extracts of Prunus persica with respect to each solvents records the in vitro activity with increasing polarity can be a potential source of natural antimicrobial and antioxidant agents.

Keywords: antioxidant activity, free radical scavenging, Prunus persica.
