This study was designed to evaluate the diuretic effects of P. farcta extract in comparison with spironolactone and hydrochlorothiazide in normal and hypertensive rats.Forty eight rats, were divided into Two groups. The First group was consist of Twelve normotensive rats, to represent the control group and normal treated group receiving 50 mg/Kg of P. farcta extract; Six rats in each group.

The Second group involved 36 hypertensive rats, were divided into six subgroups, each of six rats. The First subgroups served as a positive control, the Second, Third and Fourth sub-groups were received 25, 50, 100 mg/Kg of P. farcta fruit extract respectively. The Fifth and Sixth subgroups were received 5 mg/kg spironolactone, and 25 mg/Kg thiazide orally for a week. P. farcta extract produced a significant increase in urine flow, Sodium excretion rate, eGFR and urinary creatinine level. In addition there were significant reduction in heart rate, and serum creatinine and blood urea.
