Gastric ulcer is the most common disorder of the gastrointestinal tract, it occurs mainly in the stomach. α-pinene is a bicyclic terpene and its oil extracted from Lamiaceae, conifers, citrus and other plants. It has broad pharmacological activities. This study was done to assess the anti-ulcer activity of α-pinene against gastric ulcer in rat. This study included 6 groups with 6 rats in each group. Group 1 is healthy group and group 2 is control group (untreated ulcer group). Group 3 (positive group) was orally pretreated with 20 mg/kg ranitidine. Groups 4, 5, and 6 (experimental groups) were orally pre-treated with α-pinene at 500, 1000 and 1500 mg/kg doses, respectively. Result of this study appeared that the ulcer control group showed severe mucosal injury, while pre-treatment with α-pinene resulted in significantly (P<0.05) protection of gastric mucosal injury, good neutralizing properties, and increase in mucus production in comparison to ranitidine pretreated and ulcer control groups. In conclusions, the present results suggest that α-pinene exhibit an anti-ulcer activity against ethanol-induced gastric ulcer in rats.
