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. |
