Composition and Antimicrobial Activity of the Essential Oils of Five Taxa of <i>Sideritis</i> from Greece

Abstract

The chemical compositions of the essential oils obtained from the aerial parts of five taxa of Sideritis were analyzed using various GC-MS techniques. A total of 99 different compounds was identified, and significant differences (qualitative and quantitative) were observed between the samples. The in vitro antimicrobial activity of the essential oils against six bacteria and three fungi is also reported.
