Objective: To characterize and standardize the ethanolic extract of Adhatoda vasica (AV) and evaluate its antioxidant potential in vitro, and to study
its free radical scavenging effect in A549 cell line.
Methods: Antioxidant activity of AVE through DPPH, ABTS, superoxide radical scavenging activity, H2O2, NO and Lipid peroxidation assays were
carried out.
Results: In A549 cell line, the NO scavenging ability of AVE was analysed through NO production measurement. IC
values of ethanolic extract through
DPPH, ABTS, superoxide radical scavenging activity, H
, NO and lipid peroxidation assays were found to be 64, 200, 54, 62, 40 and 340 µg/ml,
respectively. The reducing power was found to increase in a concentration dependent manner. AVE (1 - 2µg/ml) scavenged NO radicals (11% and
28% in comparison to control).
Conclusion: The present study showed the ethanolic extract of AV to be a good oxygen radical scavenger and a natural source of antioxidants. AVE
showed significant nitric oxide radical scavenging activity in A549 cell line.
Keywords: Adhatoda vasica, Phytochemicals, Flavonoids, Tannins, Antioxidant potential.
