Objective(s):Various species of genus Trigonella are important from medical and culinary points of view. The essential oil of Trigonella torbatejamensis Ranjbar as an endemic plant in Iran has not been studied previously. The essential oil of this plant was analyzed by different methods for identification of its components. Materials and Methods: The essential oil composition of aerial parts of T. torbatjamensis was obtained by hydro-distillation and analyzed by GC-FID and GC-MS apparatus. Results: Forty components, representing 98.5 % of the total components, were identified. The pattern of the main grouped components in essential oil was: sesquiterpene hydrocarbons (70.2%), oxygenated sesquitepenes (16.5%), oxygenated monoterpenes (3.5%) and monoterpene hydrocarbons (0.5%). Germacrene –D (33.0%), bicyclogermacrene (26.0%), and viridiflorol (5.3%) were the main components of the essential oil. Conclusion: The essential oil of T. torbatjamensis Ranjbar consisted of forty components with sesquiterpene hydrocarbons as the main group of components.
