On the other hand, ellagic acid exerts antiulcer activity via the: i) inhibition of gastric H+, K + −ATPase, ii) inhibition of acid secretion, and iii) attenuation of lipid peroxidation in the gastric mucosa and myeloperoxidase in the intestinal mucosa of ethanol-induced ulcer model [50, 53]. This evidence concerns the gene MPO and ulcer disease.
