RÉSUMÉ

Piptoporus betulinus has been used in folk medicine for millennia. However, no data currently exist regarding its potential cardiovascular activity. In this work, the crude ethanolic extract and fractions (hexane, ethyl acetate, and water) with increased polarity from the partitioning process, as well as stigmasterol (the major metabolite isolated from P. betulinus), were administered orally at different doses to normotensive male Wistar rats an hour before recording mean arterial pressure, heart rate, renal blood flow, renal vascular conductance, arterial blood flow, and arterial vascular conductance. The acute oral administration of crude ethanolic extract and all fractions did not alter mean arterial pressure when compared with the control group, which received a vehicle. In addition, subchronic (14 days) oral administration of crude ethanolic extract, fractions, and stigmasterol did not alter cardiovascular parameters. In conclusion, our findings demonstrate that oral administration of organic extracts of P. betulinus did not induce cardiovascular alterations.
