- Abstract
The aim of the present study is to investigate and compare the physicochemical properties of the essential oil obtained from the oleo-gumresin of two Ferula gummosa populations from Isfahan and Fars habitats. For this purpose, the oleo-gum-resin of F. gummosa was collected from two areas in Maragh, Kashan and Eqlid, Fars. The essential oil was then extracted from the fresh oleo-gum-resin by water and steam distillation. The essential oil was analyzed quantitatively and qualitatively using GC and GC/MS devices. The appearance and physical and chemical characteristics of the essential oil of two populations of F. gummosa including their relative density, refractive index, optical rotation, and phytochemicals were investigated and compared. According to the results, F. gummosa essential oil is a transparent and colourless liquid with a turpentine odour and a green woody scent. The essential oils of two populations of Kashan and Eqlid have relative densities of 0.874 and 0.869, refractive indices of 1.4810 and 1.4795, and optical rotations of 11.35° and 23.52°, respectively. The comparison of the average physical traits of the essential oils of two F. gummosa populations shows that there is no significant difference in the characteristics of relative density and refractive index while there is a significant difference in the amount of optical rotation, which is due to the difference in the content of optically active compounds in the profiles of the two essential oil samples. Based on the essential oil analysis, hydrocarbon monoterpenes including β-pinene (71% and 68.8%), δ-3-carne (9.4% and 5.2%), limonene (2.4% and 15.6%), myrcene (3.9% and 2.4%), and α-pinene (3.6% and 3.4%) were identified as the main compounds in two F. gummosa populations from Kashan and Eqlid, respectively. The difference between two F. gummosa populations in the amount of essential oil components is related to factors such as altitude, climate and precipitation of the two habitats. Although the physicochemical properties of the essential oil of two F. gummosa populations studied are in good agreement with the international standard (ISO), the advantage of Fars F. gummosa is the high content of limonene in the essential oil, and this indicates the ability of Iranian galbanum to compete in foreign markets.
