Data of in vivo screening of antiulcer activity for methanolic extract of Vernonia elaeagnifolia DC

Abstract

The data present in this article is related to evaluation of standardized methanolic extract of Vernonia elaeagnifolia aerial parts [MEVE], a species of Asteraceae family for antiulcer potential. Antiulcer activity of MEVE (200 and 400 mg/kg, b.w., p.o.) was evaluated with ethanol and aspirin induced ulcer models and pylorus ligation induced gastric ulcer model. The antioxidant potential of MEVE was evaluated with nitric oxide radicals, hydroxyl radical and H2O2 radical scavenging assay against standard ascorbic acid to correlate antioxidant and antiulcerogenic action. MEVE significantly protects the gastric mucosa against the ethanol and aspirin induced ulcer and pylorus ligation induced ulcer challenge. MEVE had shown significant [normal control: p < 0.0001, disease control: p < 0.0001, standard: p < 0.0001] decrease in the ulcer index produced by all three models in rats as compared to the standard drug omeprazole [20 mg/kg, b.w., p.o.].The present data suggest that aerial parts of Vernonia elaeagnifolia possess significant antiulcer activity, which may attributed to its antioxidant mechanism of action.
