Phlegmarirurs saururus (Lam.) B. Øllg., an autochthonous species in our country, is used in the ethnomedicineas anaphrodisiac. Previously we demonstrated that the decoction and the alkaloid extracts of this species produce a proejaculatory effect in spinalized male rats.As a result, the objective of the present investigation was to assesswhetherthat effect was produced by its main alkaloids, sauroine and sauroxine. It is known that the ejaculatory response is regulated by the CNS in both the brain and the spinal cord, so if we make a cut at the level of T6 (spinning), we remove the brain control and let the activation of the Spinal Generator of Ejaculation. Thus, sexually experienced male Wistar rats were anesthetized and subjected to surgery to be spinalized. The animals were divided into 6 groups of 3 males each.Control group received saline, reference group was administered with 10 mg/kg of sildenafil, and treatment group received 0.1 and 1 µg/kg of sauroine or sauroxine, all given intravenously. Results showed that both alkaloids facilitate the ejaculation, in view that both produce a diminution in the Latency of Discharge (P
