Essential oil yield and compositions of sage (Salvia Officinalis L.) cultivated in different province of Turkey

Abstract

The essential oils from three Salvia species from Konya, Karaman and Elazığ locations were analyzed by gas chromatography – mass spectrometry (GC-MS). In this study, ıt was investigated essential oil yield and compositions of sage (Salvia officinalis L.) cultivated in different province Turkey (Elazıg, Karaman, Konya). The air-dried herb parts of sage (Salvia officinalis L.) were subjected to hydrodistillation for 3 h using a Clevenger-type apparatus to produce essential oil. The GC-MS analysis was carried out with Agilent 7890 GC-MS system. The relative percentages of the separated compounds were calculated from total ion chromatograms. The identification of the oil components was based on the Wiley and NIST mass spectral library. The sage production was determined as 1.7% in Konya, 1.6% in Karaman and 1.1% in Elazığ, respectively. The essential oil of the sage cultivated in Konya is 1.7% and its major components are α-thujone (15,04%), 1,8 cineole (13,46%) and camphor (8,90%). The essential oil of camphor cultivated in Karaman is 1.6 % and the major components are camphor (26.22%), α-thujone (20.02%) and 1.8 cineole (10.54). The essential oil of the sage cultivated in Elazığ is 1,1% and the major constituents are α-thujone (24,55%), 1,8 cineloe (14,42%) and camphor (11,15%). According to the results of this study, it was determined that significant differences between essential oil yield and components of sage (Salvia officinalis L.) produced in different provinces of our country were determined.
