Introduction: Peptic ulcer disease represents a worldwide health problem because of its high morbidity, mortality and economic loss. It is a very prevalent condition affecting around 10%– 15% of the general population worldwide. Most of the available antiulcer drugs are costly and have an incidence of relapse, drug interactions and several side effects upon chronic usage. Hence, the use of herbal medicine may be safe, economical and effective in such cases when drugs are used for long periods. Ethnobotanical reports showed traditional claims on the use of Cordia africana seeds for the treatment of gastric ulcers. However, the safety and efficacy of these remedies are not well known. The aim of this study is, therefore, to evaluate the antiulcer activity and safety of a crude extract of C. africana seeds in animal models.
Methods: Shade-dried seeds of C. africana were extracted by 80% methanol and dried by the rotator evaporator and lyophilized. The crude extract was used to evaluate antiulcer activity in vivo with pylorus ligation method, on Wistar albino rats weighing 230– 250g. Preliminary phytochemical screening was performed using a standard procedure. Acute toxicity study was carried out in Swiss albino mice before antiulcer activity tests.
Results: No sign of toxicity was observed upon the administration of 2000 mg/kg of the crude extract to mice. Single-dose administration of 400 and 600 mg/kg extract showed a significant reduction in the volume of secretion and acidity of the stomach (p < 0.01). The doses 400 and 600 mg/kg have reduced the ulcer score by 83.58% and 88%.
Conclusion: The result of this study showed that the hydromethanolic crude extract of C. africana has strong antisecretory and ulcer protective activities against ulcers produced by pylorus ligation.
