Gayathri Devi, S2017-03-072017-03-072010https://ir.avinuty.ac.in/handle/avu/1898Aristolochia indica is a traditionally used medicinal plant claimed to possess antioxidant, antidiabetic and anti-inflammatory activity. The present study was conducted with the purpose to evaluate the in vitro antioxidant activity in leaves and stem of Aristolochia indica. The enzymic antioxidants such as catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GR), glutathione peroxidase (GPx) and glutathione-s-transferase (GSH) and non-enzymic antioxidants (ascorbic acid, atocopherol, reduced glutathione, total carotenoids and flavonoids) were found to be present. The free radical scavenging activity (inhibition of nitric oxide and super oxide generation, in vitro lipid peroxidation and DPPH free radical scavenging and hydrogen peroxide radical scavenging activity) of different extracts of Aristolochia indica was also observed. The results obtained in the present study indicated that the Aristolochia indica might be a good source of natural antioxidant.
