Objective: In the gastrointestinal system, gastric ulcer is one of the common serious problems in human life and gives contribution against morbidity and mortality incidence. The pathophysiology of gastric ulcer is an imbalance between aggressive factor and mucosal integrity factor. Increase of aggressive factors and decrease of mucosal integrity factors have potential against developed of gastric ulcer disease. The objective of the research was to evaluate antioxidant and gastric ulcer healing effect of Orthosiphon stamineus (Benth.) leaves extract in aspirin-induced rats.

Methods: In vivo antiulcer activity of Orthosiphon leaves extract was evaluated through several parameters involves gastric acidity, number of ulcers, diameters of ulcers, ulcer index (UI), and healing ratio. Dose level of Orthosiphon leaves extract which used in this study such as 250 and

500 mg/kg, respectively. Antioxidant activity of Orthosiphon leaves extract was evaluated by 1,1-diphenyl-2-picrylhydrazyl hydrate (DPPH) method. Histopathological of the stomach was performed using hematoxylin-eosin stained.

Results: The results of the study showed that groups which given Orthosiphon leaves extract have significantly different for gastric ulcer healing compared to the control group and were supported by histopathological analysis. The Orthosiphon leaves extract also showed maximum scavenging

activity at a concentration of 100 µg/ml (58.86% inhibition) and minimum at 50 μg/ml (29.60% inhibition) with inhibitory concentration 50% (IC  )



84.54 µg/ml when compared to ascorbic acid as the standard with IC

5.08 µg/ml by DPPH method.

Conclusion: It can be concluded that from the experimental study of O. stamineus (Benth.) leaves extract has potential antiulcer activity in aspirin- induced rats model and antioxidant effect using DPPH method. Stomach tissues regeneration in gastric ulcer model might be affected by the improvement of antioxidant status.

Keywords: Orthosiphon stamineus (Benth.), Extract, Ulcer, Aspirin, 1,1-diphenyl-2-picrylhydrazyl hydrate.
