Antiulcer effect of the methanolic extract of Tamarindus indica seeds in different experimental models.

BACKGROUND

Peptic ulcer is a global health problem of the gastrointestinal tract characterized by mucosal damage secondary to pepsin and gastric acid secretion which occurs due to due to an imbalance between offensive and defensive factors.

OBJECTIVE

The present study was carried out with methanolic extract of the seed coat of Tamarindus indica Linn. to evaluate its antiulcer potential on ibuprofen, alcohol and pyloric ligation induced gastric lesions.

MATERIALS AND METHODS

Doses of 100 mg/kg & 200 mg/kg of methanolic extract wre administered orally to rats of different groups. Ranitidine at a dose of 50 mg/kg was used as a standard drug for these gastric ulcer models. The gastric content was collected and the volume was measured. The ulceration index was determined by examining the inner lining of each stomach. Furthermore, the effect was assessed by free acidity, pepsin activity, total carbohydrate (TC), protein content (PK).

RESULT

The result showed that the methanolic extract of seed coats of Tamarindus indica significantly reduce the total volume of gastric juice, free and total acidity of gastric secretion (P < 0.01) in pylorus ligation induced ulcer model as is comparable with the standard drug ranitidine. There was also a significant reduction in ulcer index (P < 0.01) as compared to control group.

CONCLUSION

The methanolic extracts of seed coat of Tamarindus indica can be used as a new source of antiulcer agent in animals.
