The essential oils obtained by hydrodistillation of green and ripe fruits, herb, flowers and roots of Smyrnium olusatrum (alexanders), have been analyzed by means of GC, GC-MS, and NMR spectroscopic methods. Roots, herb and flowers are characterized by a high content of oxygenated sesquiterpenoids, most of them furanosesquiterpenoids, while green and ripe fruits are dominated by monoterpene hydrocarbons with beta-phellandrene and alpha-pinene as major constituents. The furanosesquiterpenoids, comprising a high proportion of furanodiene and isofuranogermacrene, are present in all parts of the plant. In roots and herbs furano-eremophil-1-one is the second important furanosesquiterpenoid, whereas 1 beta-acetoxyfurano-4(15)-eudesmene was detected as a prominent component in green and ripe fruits. Additionally a new furanoeudesmane derivative has been isolated from the fruits. With the aid of 13C, 1H and 2D NMR the structure has been established as furano-4(15)-eudesmen-1-one.
