Abstract
Volatile constituents obtained from crushed fruits and aerial parts of Grammosciadium pterocarpum Boiss. (Apiaceae) by microdistillation were analyzed by gas chromatography (GC) and GC-mass spectrometry (GC-MS) systems, simultaneously. Fifteen components comprising 99.5% of the volatile oil of the fruit and twenty components comprising 97.4% of the volatile oil of the aerial parts were identified. The main constituents of the fruit volatiles were found to be linalool (68.4%) and β-pinene (22.0%), whereas caryophyllene oxide (55.1%) and β-caryophyllene (15.3%) were found to be major constituents in the volatiles of the aerial parts.
