title: Sesquiterpene coumarins from the roots of Ferula assa-foetida.
abstract: From the chloroform extract of the roots of Ferula assa-foetida, two sesquiterpene coumarins designated assafoetidnol A and assafoetidnol B were isolated, in addition to six known compounds, gummosin, polyanthin, badrakemin, neveskone, samarcandin and galbanic acid. The structures of the sesquiterpenes new compounds were established by spectroscopic methods.
