| Sumario: | The aim of this study was to determine the volatile phytochemical constituents and evaluate the antimicrobial activity of the essential oils of the leaves from <i>Croton adipatus</i>, <i>Croton thurifer</i>, and <i>Croton collinus</i>. Essential oils were extracted by hydro-distillation using the Clevenger extractor and the phytochemical analysis was determined by Gas chromatography-Mass Spectrometry (GC-MS). The antimicrobial activity was assessed using the agar diffusion and colorimetric broth microdilution methods against <i>Staphylococcus aureus</i> ATCC 25923, <i>Bacillus subtilis</i> ATCC 6633, <i>Escherichia coli</i> ATCC 25922, <i>Pseudomonas aeruginosa</i> ATCC 9027, and <i>Candida albicans</i> ATCC The essential oils from <i>C. adipatus</i>, <i>C. thurifer</i>, and <i>C collinus</i> had 46, 38, and 35 volatile constituents respectively. The main compounds determined in <i>C. adipatus</i> were β-myrcene (18.34%), while in <i>C. collinus</i> was β-caryophyllene (44.7%), and in <i>C. thurifer</i> was an unknown component (C<sub>10</sub>H<sub>16</sub>: 22.38%). Essential oil of <i>C. adipatus</i> showed a MIC against <i>B. subtilis</i> (286.4 µg/mL) and <i>C. albicans</i> (572.8 ± 0 µg/mL); <i>C. thurifer</i> against <i>S. aureus</i> (296.1 ± 0 µg/mL) and <i>B. subtilis</i> (148 ± 0 µg/mL); and <i>C. collinus</i> against <i>B. subtilis</i> (72 ± 0 µg/mL) and <i>C. albicans</i> (576.2 ± 0 µg/mL). The three essential oils of Croton species demonstrated <i>in vitro</i> antimicrobial activity against a strain of bacteria or fungi. |
