Resumen:
Hydrodistilled oils of B. spartioides from three populations of Argentina (Nortwest, Central and Patagonia areas) were analyzed by using GC and GCMS. Thirty nine compounds were identified inthe oils and a relatively high variation in their contents and in their antimicrobial activity was found. The main constituents of the oils were cmphor, limonene, citronellal, carvone and spathulenol. The oil was tested against ten Gram positive and Gram negative bacteria and against the yeast Candida albicans. The best antimicrobial activity of the oils fo B. spartioides was against S. aureus and B. cereus while P. aeruginosa was the most resistant bacteria to all the oils.
