The bioactive principles of the plants have potent therapeutic value. Thus plants serve the humans and maintain their health. In the present study, the ethanolic and aqueous thorn extracts of Prosopis juliflora were assessed for antioxidant activity and nitric oxide scavenging activity. The phytochemical analysis revealed the presence of flavonoids, saponins, glycosides, terpenoids, coumarins in ethanolic and aqueous thorn extracts of Prosopis juliflora. At higher concentrations, aqueous thorn extracts of Prosopis juliflora exhibited significant antioxidant activity by DPPH (1, 1 diphenyl 1-2-picric hydrazine) radical scavenging method whereas ethanolic extracts of Prosopis juliflora thorns exhibited significant antioxidant activity by ABTS (2, 2’-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) free radical scavenging method. Also the ethanolic thorn extracts of Prosopis juliflora showed a significant activity by Nitric oxide scavenging method. The presence of the secondary metabolites attributes the antioxidant activities.
