ABSTRACT

 

Oxidative stress caused by free radicals is associated to various diseases. Modern research is directed towards finding naturally-occurring antioxidants of plant origin. The aim of the present study was to evaluate the in vitro antioxidant activities of punica granatum rind extracts of ganesh variety. The present investigation was to examine the free radical scavenging activity of various extracts of punica granatum rind by different in-vitro methods. The antioxidant activity was evaluated by DPPH assay, FRAP assay, Hydrogen peroxide radical scavenging activity, Nitric oxide radical scavenging activity. The methanolic extract of punica granatum rind was found to more effective in the radical scavenging activity. All the above invitro studies clearly indicate that the methanolic extract of punica granatum rind has a significant antioxidant activity. These invitro assays indicate that this rind extracts is a better source of natural antioxidant, which might be helpful in preventing the progress of various oxidative stresses and also support the ethnomedical use of this rind to promote good health for humans.

Keywords: Antioxidant, oxidative stress, free radicals, punica granatum rind, DPPH, FRAP.
