Distribution Profile of Volatile Constituents in Different Parts of Astrodaucus orientalis (L.) Drude

The volatile oils of stem, umbels, fruits and roots of Astrodaucus orientalis (L.) Drude (Apiaceae) growing wild in Iran were obtained by hydro-distillation and analyzed by GC-MS. The main components of the oils from the stem were sabinene (23.1%), a -pinene (16.4%) and fenchyl-acetate (7.5%). Sabinene (25.6%), b -pinene (22.3%) and a -copaene (16.1%) were the main constituents of the volatile oils of the fruits. While a -copanene (26.1%), b- pinene (15.3%) and sabinene (13.7%) were the major components of the volatile oils of the umbels (flowers), that of the roots were mainly composed of anisole (37.9%), bornyl acetate (36.9%) and geranyl tiglate (11.4%).
