The aerial parts of Selaginella lepidophylla (Hook. et Grev.) Spring, are used in Mexican folk medicine to treat renal diseases. The aim of this study was to measure the diuretic response of an aqueous extract (200 mg/kg) and alkaloids fraction at different doses (10, 40 y 100 mg/kg) of this plant and compare it with that induced by furosemide (4 mg/kg). Extract, alkaloids fraction, furosemide and vehicle were administered orally to adult rats and the effects in sodium, potassium and water balance were measured. The extract, the alkaloids fraction and the furosemide produced important and significant increments in urinary excretion of sodium, potassium and water with respect to control group. This increment was dose dependent of the alkaloids fraction, the highest dose produced a major effect. Potassium excretion increased but it was less than the one induced by furosemide. These results suggest that the aqueous extract and rich fraction in alkaloids from S. lepidophylla induce diuretic response.
