چکیده :

Prangos ferulacea is a medicinal plant that grows in central Asia and is appreciated because of its value in medicine, perfumery, and forage industries. In order to gain the optimum oil yield of P. ferulacea, the essential oils of individuals were isolated from the aerial parts by steam distillation and hydrodistillation methods 44 days after the leaf emergence. The oils were analyzed by capillary GC (Gas Chromatography). The extraction yields from the aerial parts of P. ferulacea were found to be 0.16% and 0.29% for steam distillation and hydrodistillation, respectively. Thirty-tow components, comprising 99.98% of the total oil, were identified at species individuals, in which (E)-caryophyllene (47.45%) for steam distillation method and, α-humulene (9.89%), spathulenol (7.26%), linalool (5.15%), and δ-3-carene (3.73%) for hydrodistillation method were recognized as the major components. Based on our findings, essential oil yields vary considerably and are influenced by extraction methods. So that, by hydrodistillation method both quantity and quality of oils can strongly enhance in the species.
