Seven new sesquiterpene esters plus other known substances were isolat
ed from the aerial part of Ferula linkii-TF and characterized. Four se
squiterpene coumarin ethers (colladin, colladinin, nevskin and umbelli
prenin) were also obtained for the first time from this plant. Compari
son with compounds obtained from plants of F. linkii from Gran Canaria
generated some potentially significant chemosystematic data.
