Evaluation of the antiulcer activity of the aqueous stem bark extract of Balanites aegyptiaca L Delile in Wistar rats

Balanites aegyptiaca L. Delile (Zygophyllaceae) is a perennial tree that is mostly found in Africa, south Asia and most desert environments. Decoctions of its stem barks are used in northern Nigeria for the treatment of ulcers and stomach issues. Other folkloric uses include treatment of wounds, malaria, dysentery, asthma, and fever.The present study evaluated the antiulcer activity of the aqueous stem bark extract of Balanites aegyptiaca in Wistar rats.The antiulcer activity of the aqueous stem bark extract of Balanites aegyptiaca (125, 250 and 500 mg/kg, p.o.) was evaluated in ethanol, indomethacin, pylorus ligation and acetic acid-induced ulcer models in rats. Parameters such as mean ulcer indices and percentage ulcer inhibition were assessed in ethanol, indomethacin and acetic acid-induced ulcer models while gastric volume, pH, and titratable acidity were evaluated in the pylorus ligation ulcer model.The extract at the doses of 125, 250 and 500 mg/kg caused a significant (p 0.01), dose dependent reduction in mean ulcer indices in the ethanol and indomethacin ulcer models. A significant dose dependent reduction in mean ulcer indices were also observed after three (p 0.01) and seven (p 0.001) days of treatment with the extract in acetic acid-induced ulcer model. In pylorus ligation model, the gastric secretion parameters (gastric volume, pH, and titratable acidity) showed no alteration in the different doses of the extract when compared to the control.Our study showed that the aqueous stem bark extract of Balanites aegyptiaca possesses gastroprotective and ulcer healing properties and therefore not only provides scientific evidence for its folkloric use in the treatment of ulcers but also showed evidence that it may be used in the development of a new phytotherapeutic formulation for the treatment of peptic ulcer.
