Diuretic activity of root extracts of dalbergia spinosa roxb.

The benzene, alcoholic and aqueous root extracts (75mg/kg each)of Dalbergia spinosa Roxb were studied for its diuretic activity by using male albino rats by adopting the method of Tipschitz. The alcoholic extract increased the urine volume and electrolytes sodium, potassium and chloride, which is similar to the standard drug Furosemide (100mg/ kg) by inhibiting sodium, potassium, and chloride ion co-transport at thick ascending loop of henle. The present study showed that the alcoholic extract has significant diuretic activity comparable with standard drug Furosemide in producing urinary output and excretion of sodium,potassium and chloride in mEq/ lit/ 6 hrs.
