Antioxidants help to deal with oxidative stress, caused by free radical damage. The present study highlights the antioxidant activity of methanol extract of P. roxburghii by its DPPH free radical scavenging potential. Various phytoconstituents namely alkaloids, flavonoids, saponins, glycosides, coumarins, quinones, tannins and steroids were detected. A marked radical scavenging activity was observed and found to be dose dependent. The activity of extract was found to be slightly lower as compared to the scavenging activity of ascorbic acid. Though in vitro antioxidant assay has been carried out, in vivo tests remains to be done.
