Phytochemical Analysis of Essential oil of Tanacetum parthenium L. with Hydro-distillation and Steam Distillation

Tanacetum parthenium L. known as feverfew is a medicinal herb which is found in many old gardens. It has been used in folk medicine for reducing fever. Feverfew is a member of the daisy family; it is used primarily to prevent migraine headaches and to treat rheumatoid arthritis.It hasa colorless essential oil that contains one or more of the sesquiterpene lactones as active principle. Tanasetum parthenium cultivated in Iran, were extracted with hydro-distillation and steam distillation and their chemical essential oils composition were  investigated by GC/MS. Major components obtained in hydro-distilled method were camphor (36.2%), isoborneol (20.3%),  bornyl acetate (14.3%), champhene (8.1%),p-cymene(5.1%) and in steam distilled method were camphor  (20.9%), bornyl acetate (14.24%), isobornyl isovalerate (7.1%), bornyl 2-methylbutyrate (5.9%),p-allylanisole (6.3%). The yield of essential oil with hydro-distillation was 0.05% and for steam distillation were 0.12%.
