Introduction: Bixa orellana L. is a plant that grows in Cuba, to which medicinal properties are attributed. Material and Methods: An experimental study was carried out in order to determine the antimicrobial action of ethanolic extracts and dyes of B. orellana leaves against Candida albicans, Staphylococcus aureus, Escherichia coli, and Pseudomona aeruginosa. The macrodilution method was used and the concentration minimum germicide was determined expressed in dilutions. Stumps of international reference from American Type Culture Collection of E. coli, S. aureus, P. aeruginosa and C. albicans were used. Results: The dyes to 10% and 20% of the leaf showed inhibitory activity against S. aureus in dilutions up to 1:8 and 1:32 respectively; in E. coli; the dye to 10% presented activity up to 1:8, the dyes were not active against P. aeruginosa and C. albicans. The flowing extract to 50% showed inhibitory activity in front of S. aureus up to 1:4. The flowing extract to 50% and the dyes of the leaf to 10% and 20% was active in front of S. aureus to inferior concentrations with regard to the rest of the microorganisms, but they lacked antimicrobial activity in front of C. albicans and P. aeruginosa. Conclusions: S. aureus turned out to be the most sensitive germ to the pharmaceutical forms studied to smaller concentrations minimum germicides expressed in the dilutions. The dye to 10% showed a bigger spectrum of antimicrobial activity. The dye to 20% was the most effective.
