Tanacetum pinnatum Boiss. is a medicinal plant belongs to the family Compositae or Asteraceae. The genus Tanacetum contains, totaling over 200 species and distributed over West Asia and Europe. 26 species are in Iran that 12 species are native. In traditional medicine, this herb is used as anti-allergic and anti-inflammatory drugs and for the treatment of some digestive problems. In this study, a sampling of the plant was done in the flowering stage from Kordestan-Chenareh (Veleh) region. The essential oil of the plant was isolated by Clevenger s apparatus and the components were analyzed by a gas chromatography/mass spectrometric (GC/MS). The results showed that the 14 components that represented 95.48% of the total essential oil composition were identified. The most predominant were beta-Phellandrene (20.03%), Chrysanthenyl acetate (17.78%), 1, 8-cineole (13.31%), Borneol (10.08%), Bornyl acetate (8.33%), and Camphene (6.40%). Due to the components of the essential oils, this plant can be used for the pharmaceutical industry and the breeding programs.
