Abstract: These seeds have been traditionally used for various diseases like dysentery, diarrhoea, piles, keeping in mind of their traditional value our present study was to explore wild Punica granatum seeds for its antioxidant and antiulcer potential. The phytochemical screening of the ethanolic seed extract indicates the presence of triterpenoid, sterols, alkaloids, flavonoids, tannins and coumarin glycoside. Antioxidant activity of the wild Punica granatum ethanolic seed extract was measured by 1,1-diphenyl-2-picrylhydrazyl and hydrogen peroxide free radical scavenging method. Further it was evaluated for its anti-ulcer activity by pyloric ligation model in wistar albino rats. Gastric volume, ulcerative index and free and total acidity were measured in this model. The extract showed maximum scavenging activity i.e., 82.80±0.267 and 74.91±0.235 at 100 μg mL-1 by 1,1-diphenyl-2-picrylhydrazyl and hydrogen peroxide method respectively as compared to the standard (ascorbic acid) in case of quantitative analysis and showed yellow coloration with 1,1-diphenyl-2-picrylhydrazyl scavenging radical in case of qualitative analysis. In pyloric ligation method, the extract showed optimum percentage inhibition of 74.51% at 100 μg mL-1 which was comparable to the standard (ranitidine). The present study concludes that wild Punica granatum ethanolic seed extract possesses significant antioxidant and anti-ulcer activities.
