Medicinal plants are an important natural source in the search for new compounds with pharmacological activities of interest. Senna alata (Caesalpinaceae) grows in Cuba and has a wide popular use.The in vitro antimicrobial activity of different formulations prepared from this species was evaluated.

The antimicrobial potential of S. alata, specially the antimicrobial activity of the fluid extract with menstruum 70 % was proved. The kynetics of the antimicrobial activity corroborated the results obtained that justified the traditional use of this medicinal plant and, at the same time, allows the preparation of ointments with a marked dermatophytic activity.
