Chemical Composition of the Essential Oil from Roots of Bifora testiculata (L.) Spreng. Obtained by Microwave Extraction Method

Two species of genus Bifora are found in Iran, namely Bifora testiculata(L.) Spreng. (Syn: Coriandrum testiculatum L.) And B.radiansM.B. . B.testiculatais an annual herb with typical aroma growing along the borders of the fields, especially in chalky soils of Central Anatolia [1]. It was reported that B.radians was found to be rich in alkanals and alkenals [2]. Additionally antimicrobial andinsecticidal activity studies were carried out on this species [3]. The present work presents the chemical composition of the essential oil of roots of B.testiculatagrowing wild in Ilam, in July 2015. The yellowish oil were obtained by solvent free microwave extraction method and analyzed by GC and GC/MS. Thirty- nine components in the root oil of B.testiculatawhich represented about 94.4% of the total oil, were identified. The root oil of the plant consisted of one monoterpene hydrocarbon (0.06% ), nine oxygenated monoterpenes (24.9% ), four sesquiterpene hydrocarbons (1.4% ), four oxygenated sesquiterpenes (8.3% ) and 21 non terpenoid compounds (59.7 %). The major components of this oil were (E)-2- dodecenal (31.6%) and thymol (15.5%).
