Background: Salvia L., the largest genus of Lamiaceae, includes about 1000 species, widespread throughout the world. This genus is represented, in Turkish flora, by 99 species and 113 taxa, 58 of which are endemic. Some members of this genus are of economic importance since they have been used as herbal tea, flavouring agents in perfumery and cosmetics. Some sage (Salvia L.) species has been credited with a long list of medicinal uses: e.g. spasmolytic, antiseptic, astringent. Objective: In present study, essential oil composition of some sage (Salvia L.) species cultivated in Izmir (Turkey) was investigated. Sage species have recently become more common in Turkey and sage cultivation is increasing especially in the Aegean Region. Material and Methods: The species of Salvia fruticosa Mill., Salvia officinalis L., Salvia sclarea L., hybrid (Salvia fruticosa Mill. x Salvia officinalis L.) and Salvia dichroantha L. were used in the study. Essential oils were extracted according to hydro distillation method with clevenger type apparatus and analyzed using GC-FID and GC-MS system. Results: Essential oil contents of Salvia fruticosa MM. was 3.86%, Salvia officinalis L. 2.42%, Salvia sclarea L. 0.5%, Salvia fruticosa Mill. x Salvia officinalis L. 2.84% and Salvia dichroantha L. 0.19%. The number of components in essential oils were detected 22, 16, 14, 20 and 16 respectively. The chemical composition of the essential oils in Salvia fruticosa Mill. 1,8-cineole (57.18%), Salvia officinalis L. beta-thujone (34.59%), Salvia sclarea L. linalyl acetate (46.77%), Salvia fruticosa MM. x Salvia officinalis L. 1,8-cineole (21.42%) and beta-thujone (18.37%) and Salvia dichroantha L. beta- caryophyllene (23.11%) and sabinyl acetate (21.87%).

Primary and secondary metabolites, which are natural products produced by plants, are mainly used, either directly or indirectly, in industries. These are active substances, for example etheric oils (essential oils, essences), alkaloids, tannins, bitter substances, etc., that are predominantly involved in plant metabolism. They increase the body's defence system, support the functions of organs and accelerate healing. Thus, they have positive effects on the functions of certain tissues and organs. In this study, some bioactive and biochemical compounds, dry matter, total antioxidant activity, total flavonoid and total phenolic content, macro-micro and heavy metal content, essential oil yield and content in Origanum onites and Origanum dubium species were determined. It was found that total ash (10.61-12.03%), dry matter (38.24-43.47%), total antioxidant activity (121.41-162.17 mu mol TE g-1), total phenolic content (187.04-192.25 mg GAE g-1), total flavonoid content (10.01-17.57 mg QE 100 g-1), chlorophyll amount (23.26-23.30 dx) and NBI (the Nitrogen Balance Index) (13.90-28.23 dx) were higher in O. dubium than in O. onites. Yield of essential oil was determined between 3.130 and 3.240 in O. onites and O. dubium species, respectively. Carvacrol (78.24%), gamma-terpinene (6.650%) and cymene (3.950%) components were found to be dominant in the essential oil of O. onites. On the other hand, the main components of essential oil obtained from O. dubium species were carvacrol (22.01%), gamma-terpinene (23.55%), cis-sabinene hydrate (13.90%), terpinen-4-ol (8.500%), alpha-terpinene (4.94%), cymene (4.94%) and trans-sabinene hydrate (3.35%).
