Meneghetti, Auteur ; Morgana N. Teske, Auteur Année de publication : 2012 Article en page(s) : pp. 241-244 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Piper xylosteoides Essential oil Safrole Antibacterial activity Résumé : In our continuous search for naturally occurring compounds of scientific and technological relevance, the chemical composition and antibacterial activity of the essential oils of two populations of Piper xylosteoides from Santa Catarina, Brazil, is described. Both oils showed a very high safrole concentration, being the highest value associated to the sample collected in Orleans (84.1%). As the second major compound, the monoterpene α-pinene was present with the highest concentration (15.3%) in the São Bonifácio sample. The antibacterial activity was examined towards both Gram-positive and Gram-negative bacteria. The oils showed weak activity against the bacteria tested. This species can be considered a new economically important natural source of the arylpropanoid safrole.
