OBJECTIVE: The study is to investigate the diuretic and antiurolithiatic activities of ethanolic leaf extract of Annona squamosa Linn. in experimental animals. MATERIALS AND METHODS: For both studies, Wistar albino rats and two doses of extract (250 and 500 mg/kg) were used. Diuretic activity was evaluated by Lipschitz model. Urine volume and urine pH were noted, the concentration of sodium and potassium was estimated by flame photometry, and diuretic index, natriuretic index, and Lipschitz values were calculated from the results. Furosemide was used as a positive control. Ethylene glycol-induced urolithiasis model was used for antiurolithiatic study. Urine volume, urine pH, body weight, and biochemical parameters such as calcium, urea, uric acid, and creatine both from serum and urine were estimated. Antioxidant parameters and histopathological analysis of the kidney were evaluated. Cystone was used as a positive control in this study. Results were expressed as mean ± standard error of mean. Statistical analysis was carried out using one-way analysis of variance, followed by Dunnett's multiple comparison tests. RESULTS: In both diuretic and antiurolithiatic studies, both doses of the extract showed efficacy, and the dose of 500 mg/kg has shown a significant effect compared to positive control and negative control. CONCLUSION: The dose of 500 mg/kg showed a promising diuretic and antiurolithiatic activity.
