Gastroprotective effect of the iridoid fraction from Barleria prionitis leaves on experimentally-induced gastric ulceration.

Abstract Aim To study the gastroprotective effect and in vivo antioxidant potential of a standardized iridoid fraction from B. prionitis leaves (BPE) against different gastric ulcer models in rats. Method The standardized iridoid fraction from BPE at 50, 100, and 200 mg/kg body weight was administered orally, twice daily for 5 days for prevention from aspirin, ethanol, cold-restraint stress (CRS), and pylorus ligation (PL)-induced ulcers. Estimation of the antioxidant enzyme activity was carried out in a CRS-induced ulcer model, and various gastric secretion parameters including volume of gastric juice, acid output, and pH value were estimated in the PL-induced ulcer model. Results BPE showed a dose-dependent ulcer protective effect in PL (18.67%–66.26% protection), aspirin (24.65%–63.25% protection), CRS (20.77%–59.42% protection), and EtOH (16.93%–77.04% protection)-induced ulcers. BPE treatment in PL-rats showed a decrease in acid-pepsin secretion, and enhanced mucin and mucosal glycoproteins. However, BPE reduced the ulcer index with significant decrease in LPO ( P P P Conclusion The data shows that the iridoid fraction from BPE possesses anti-ulcerogenic and antioxidant potential.
