Neoglaziovia variegata (Arruda) Mez (Bromeliaceae) is a medicinal plant popularly known as "caroa." The leaves are made up of highly resistant fibers, which is of great commercial value to the handicraft and textile industry. Some studies have demonstrated that ethanolic extract of N. variegata have gastroprotective properties. This study aimed to investigate the gastroprotective activity and cytoprotective mechanisms of ethyl acetate (Nv-AcOEt), hexane (Nv-Hex), and chloroform (Nv-CHCl3) fractions of N. variegata leaves. The gastroprotective activity of Nv-AcOEt, Nv-Hex, and Nv-CHCl3 was evaluated using the ethanol and ethanol/HCl-induced gastric injury model. To elucidate the gastroprotective mechanisms, the functions of prostaglandins (PGs), nitric oxide (NO), and KATP channels were evaluated. In addition, the nonprotein sulfhydryl groups and the mucus content in the gastric tissues were analyzed. All fractions of N. variegata leaves at oral doses of 100, 200, and 400 mg/kg significantly decreased ethanol and ethanol/HCl-induced gastric lesions,...
