Abstract
| - The roots of the nonpoisonous chemotype of giant fennel (Ferula communis) from Sardinia afforded anovel cadinanetriol (1), whose structure was established by spectroscopic data and confirmed by synthesisfrom the E,E-Δ 1(10),5 germacradiene allohedycariol. A number of known compounds were also identified.Despite the lack of morphological differences, a broad chemical diversity exists within giant fennel,underlying the contrasting data on its poisonous properties.
