Volatile constituents of different parts (roots, stems and leaves) of Smyrnium olusatrum L.

Smyrnium olusatrum L. is a biennal plant growing in western and southern Europe. Several phytochemical studies have identified flavonoids, phenolic acids and sesquiterpene lactones as main constituents. In this work the root, stem and leaf essential oils of Smyrnium olusatrum L. (Umbelliferae) collected in Urbino (Marche, Italy) were studied by GC and GC‐MS. Myrcene (1, 13 and 14%), β ‐phellandrene (34, 17 and 9%), β ‐caryophyllene (1, 3 and 12%), furanodiene (19, 8 and 17%), curzerene (13, 6 and 12%), germacrene B (7, 14 and 10%) and germacrone (8, 7 and 8%) were identified as the major components in the root, stem and leaf oils, respectively. SPME analysis of fresh material of the same different organs showed β ‐myrcene (3, 21 and 36%), β ‐phellandrene (25, 34 and 12%), β ‐caryophyllene (1, 7 and 22%) and furanodiene (4, 7 and 7%) as typical components in the headspace of fresh roots, stems and leaves, respectively.
