Abstract In spite of the great advances in chemotherapeutics, infectious diseases are still one of the leading causes of death in the world. Thus, development of new antimicrobial compounds against different microorganisms and with new mechanisms of action is becoming critically important. In our continuous search for new antimicrobial molecules we screened the culture broth of several soil microorganisms. A Beauveria isolate showed promising activity and we isolated and determined the structure of a phenolic glycoside (6-Methyl-1,2,4-trihydroxybenzene-1-O-β-D-4´-methyl-glucopyranoside)never before reported in this species.
