Background: An increasing demand for natural additives has shifted the attention from
synthetic to natural antioxidants. As leafy vegetables are found to be good source of antioxidants
and the present study is to examine the antioxidant potential and antimicrobial
activity of leaf extracts of Pimpinella tirupatiensis.
Methods: Antioxidant potential of leaves of P. tirupatiensis was studied using different
methods like DPPH, nitric oxide, hydrogen peroxide scavenging activity. Reducing power
and antimicrobial activity was estimated by using both gram positive and gram negative
microorganisms by using DMF as solvent.
Results: The aqueous extracts showed maximum scavenging activity of DPPH followed by
nitric oxide, hydrogen peroxide and reducing power respectively. Benzene and alcoholic
extract showed maximum antimicrobial activity.
Conclusion: Substantial amounts of antioxidants including vitamins C and E, carotenoids,
flavonoids, phenols and tannins etc. can be utilized to scavenge the excess free radicals
from the body.
