Antimicrobially active terpenes cause K+ leakage in E. coli cells / Shane G. Griffin in The journal of essential oil research, Vol. 17 N° 6 (Novembre-Décembre 2005) 

Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 6 (Novembre-Décembre 2005) . - pp. 686-690 Titre : Antimicrobially active terpenes cause K+ leakage in E. coli cells Type de document : texte imprimé Auteurs : Shane G. Griffin, Auteur ; S. Grant Wyllie, Auteur ; Julie L. Markham, Auteur Année de publication : 2006 Article en page(s) : pp. 686-690 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Antimicrobial  activity  Potassium  ion  leakage  1,8-cineole  (−)-carvone  (−)-(cis,trans)-carveol  (±)-terpinen-4-ol  (±)-α-terpineol  (−)-myrtenol  (±)-trans-p-menth-6-ene-2,8-diol Résumé : The known antimicrobially active oxygenated terpenes, carvone, terpinen-4-ol, α-terpineol, carveol and myrtenol were found to cause significant K+ leakage from E. coli cells. In contrast, the relatively inactive oxygenated terpenes, 1,8-cineole and p-menth-6-ene-2,8-diol, did not cause significant K+ leakage. Slight structural differences between active terpenes were found to affect the rate of K+ leakage from E. coli cells. The membrane permeabilizing effect of the active terpenes is considered a significant factor in their antimicrobial activity.
