Identification of volatile oil components from aerial parts of Trigonella torbatjamensis Ranjbar by GC-FID and GC-MS

Abstract

<em>Objective(s)</em>:Various species of genus <em>Trigonella</em> are important from medical and culinary points of view. The essential oil of <em>Trigonella torbatejamensis</em> 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. <em>Materials and Methods</em>: The essential oil composition of aerial parts of <em>T. torbatjamensis </em>was obtained by hydro-distillation and analyzed by GC-FID and GC-MS apparatus. <em>Results:</em> 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. <em>Conclusion:</em> The essential oil of <em>T. torbatjamensis</em> Ranjbar consisted of forty components with sesquiterpene hydrocarbons as the main group of components.
