Determination of The Essential Oil Components of Some Sage (Salvia Sp.) Species Naturally Distributed in The Isparta Province

Aim of the study: This study was performed to determine the essential oil components of Salvia tomentosa Mill., Salvia argentea L. and Salvia bracteata Bank et Sol. Area of study: The study was carried out in two districts (Eğirdir and Şarkikaraağaç) located at Isparta province in Turkey. Material and methods: The isolation of essential oil components was performed from shoots with leaves and flowers. Qualitative analysis of essential oils was carried out by using a Shimadzu 2010 Plus GC-MS device. The identification of the constituents was carried out by comparing the retention index (RI) and mass spectral data (MS) to those reported in the literature. Main results: As a result of the GC-MS analysis, the major components of the essential oil were (-)-caryophyllene oxide (49.56%), β-vatirenene (7.87%), and α-Muurolol (6.78%) in S. tomentosa, sclareol (40.01%), germacrene-D (13.93%) and β-pinene (11.93%) in S. argentea and eucalyptol (1,8-cineole) (16.6%), β-pinene (14.7%) and cembrene (10.88%) in S. bracteata. Sclareol, which was determined at a high concentration in S. argentea in this study, is an economically valuable component that is widely used as flavoring in food and tobacco industry and as a perfume ingredient in the cosmetic industry. Highlights: According to this study, the cultivation of S. argentea can provide high economic returns
