The possibilities of the application of some species of sage (Salvia L.) as auxiliaries in the treatment of some diseases

The chemical composition of four essential oils of four species of sag-e (Salvia officinalis L., Salvia pratensis L., Salvia glutinosa L. and Salvia aethiopis L.) are examined by GC-FID and GC-MS analysis. The presence of some component,:, in the essential oil (mono- and sesquiterpene) determines the pharmacological effects and therapeutical application of a plant species. Salvia officinalis L. gives the highest yield of oil (1.1%), while the lowest is in Salvia pratensis L. (0.1%). The investigations included the determination of the antimicrobic activities of the essential oils by the diffusion method and the oil of Salvia pratensis L. proved to have the highest activity.
