Abstract:
The chemical composition of the essential oil of Salvia sharifii growing wild in Iran was investigated by gas chromatography-mass spectrometry (GC-MS). Thirty-nine components representing 84.5 % of the oil were identified. Caryophyllene (12.8 %), germacrene D (9.5 %), trans-isolimonene (7.0 %), spathulenol (6.9%), bicycloegermacrene (5.6 %), caryophyllene oxide (5.5 %) and 1,8-cineol, co-eluted with limonene (4.2 %) were the main components of the oil. The close morphological characters of S. sharifii and S. macrosiphon promoted us to investigate them, particularity to understand if they are chemically identical or different. The GC-MS analytical results of the essential oil of S. sharifii were compared to those previously reported for the oil of S. macrosiphon. Our analytical results, suggested that although S. sharifii and S. macrosiphon belong to the same botanical group, they are not chemically identical.
