Assafoetidin and ferocolicin, two sesquiterpenoid coumarins from ferula assafoetida regel

Tetrahedron Letters

Phytochemical investigation of the gum resin of Ferula assafoetida resulted in the isolation and characterization of a new sesquiterpenoid coumarin, Saradaferin (1) named as [Decahydro-(3-α-hydroxy-4,4,10- trimethyl-8-methylene-9-naphthnyl)-α-hydroxymethyl] ether of umbelliferone.
