VOLATILE CONSTITUENTS OF THE AERIAL PARTS OF TERATAENIUM LASIOPENTALUM (BOISS.) MANDEN., STEMS AND LEAVES OF DOREMA AMMONIACUM D.DON. AND LEAVES, FRUITS AND STEMS OF LEUTEA PETIOLARE (DC.) M.PIMEN FROM IRAN
The Composition of the essential oils from three Umbelliferae species of Iran , Tetrataenium lasiopetalum (Boiss.) Mandem ., Dorema ammoniacum D.Don., which is endemic to Iran, and Leutea petiolare (DC.) M.Pimen. obtained by hydrodistillation were analyzed by GC and GC/MS. Germacrene D (17.72%) and (E,Z) farnesol (12.58%) were the main components in the oil of aerial parts of T. lasiopetalum. The major compound in the stem oil of D. ammoniacum was α-muurolol (13.68%), whereas the leaf oil contained (E)-β-ocimene (30.94%), γ-terpinene (11.09%), p-cymene (10.03%) and (Z)-β-ocimene (7.11%). Terpinolene (13.93%, 8.28% and 10.27%) , (E)-β-ocimene (10.24%, 24.63% and 10.46%) and endo-fenchyl acetate (15.1%, 7.42% and 7.57%) were the main constituents in the leaf, fruit and stem oils of L. petiolare respectively.
