Abstract: The chemical composition of the essential oils of sage (Salvia officinalis L.) has been investigated by GC-MS technique. Three ways of distillation, using a Clevenger-type apparatus were applied for their obtaining: I - classical hydrodistillation (CD), II - the 800W microwave hydrodistillation (MWD) and III - solvent free microwave distillation at 800W (SFMWD). Using the microwave, the distillation time was shortened to 75 min. (MWD) and 64 min. (SFMWD). As a characteristic component of the essential oil of sage, cis-thujone is mostly present in CD oil (19.1 %). A slightly lower content (18.8 %) was found in the SFMWD oil, while the lowest content (18.0 %) was observed in the MWD sample. The highest content of monoterpenes was identified in the MWD oil, followed by CD and SFMWD oils. Sesquiterpenes dominate in the SFMWD oil, followed by CD and MWD. The content of diterpenes (only manool) is the largest in the sample CD, followed by SFMWD and MWD.
