    ObjectivesSweet potato (Ipomoea batatas) is accredited as a functional food because of its nutraceutical compounds. These dietary components may help heal lesions and ulcer scars in the stomach. This research was designed to examine the antioxidant and antiulcerative potential of sweet potato (red skin, white flesh) against aspirin-induced gastric ulcers in a rabbit model.MethodsSweet potato samples were analyzed for in vitro analysis, such as 2,2-diphenyl-1-picrylhydrazyl assay, total phenolic content, and total flavonoid content. In a bioefficacy study, rabbits were divided into five groups (n = 6) in which G0 received the standard diet only, G1 150 mg/kg aspirin, G2 20 mg/kg omeprazole, G3 1000 mg/kg aqueous extract of sweet potato, and G4 1000 mg/kg ethanolic extract of sweet potato. After completion of the trial, the animals were decapitated and examined for antiulcer parameters, serum analysis, and hematologic parameters.ResultsThe mean values for 2,2-diphenyl-1-picrylhydrazyl, total phenolic content, and total flavonoid content were 57%, 927 mg gallic acid equivalent/100 g, and 1901 µg quercetin equivalent/g, respectively. The values for gastric volume, acid output, ulcer scores and index, total oxidant status, white blood cell count, and lymphocyte count were increased significantly (P < 0.05) for the positive control group compared with G2, G3, and G4. Gastric pH and body weight at the end of the experiment were significantly reduced for the positive control group (P < 0.05) compared with G2, G3, and G4. Histology test results of gastric tissues in G1 depicted severe epithelial damage compared with G2, G3, and G4.ConclusionsThe results for the antiulcer parameters ascertained the antiulcer activity of sweet potato in aspirin-induced gastric ulcer models.Copyright © 2022 Elsevier Inc.
