Resumen:
SUMMARY. In the present work, fractions of the ethanolic crude extract of Carijoa riisei (Octocorallia) collected at South Brazil (Santa Catarina island) were tested against different bacterial, fungal and protozoal pathogens. The n-hexane fraction (HF) showed a moderate activity against S. aureus in the disk diffusion method, and inhibited 43.4 and 35.9 % the growing of T. cruzi epimastigotes and L. braziliensis promastigotes, respectively. The steroid pregna-1,4,20-trien-3-one was isolated from HF and presented in vitro antiprotozoal activity against the extracellular forms of the parasites at 50 μM, showing 50.4 % growth inhibition of L. braziliensis and 42.4 % growth inhibition of T. cruzi.
