Gastroprotective Activity of Methanol Leaves Extract of Barleria prionitis Linn. on Ethanol and Indomethacin Induced Ulcer in Rats

Abstract

Aims: Barleria prionitis L. (Family Acanthaceae) is a medicinal plant found road side in India and whole plant or its various parts like leaves, root, bark, stem and flowers are used traditionally for various treatments like toothache, inflammation, boils, glandular swellings and ulcer. Leaf juice is useful in gastric ulcer. Here, we attempt to prove the use of this plant as gastroprotective agent. Study Design: This study was conducted to evaluate the antiulcer activity of methanol extract obtained from the leaves of Barleria prionitis Linn. Place and Duration of Study: The experiments were conducted at Pharmacology lab of Institute of Pharmaceutical Sciences, Kurukshetra University during the period of July 2012 to December 2012. Material and Methods: Antiulcer activity was performed using the protocols of ulcer induced by ethanol and indomethacin at two different doses (250 and 500mg/kg). Parameters like volume of gastric juice, pH, free acidity, total acidity, aspartate amino transferase (AST) and alanine amino transferase (ALT) were also determined in ethanol induced ulcer model. Results: The reduction in ulcer index in Barleria prionitis treated animals was found to be statistically significant (P=.05), when compared with control groups in both the models. Significant changes were observed in total acidity only at dose 500mg/kg only and changes were significant in AST, ALT levels at both the doses. Other parameters showed non-significant results. Conclusion: The results of the present study show that the methanolic extract of Barleria prionitis L. possess antiulcer activity. This work supports the traditional use of this plant in treating gastric ulcer.
