RESUMEN
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.

Two monoterpene coumarins, designated ferulagol A and B, as well as three known monoterpene coumarins and three sesquiterpene lactones were isolated from the chloroform extract of the roots of Ferula ferulago. The structures of ferulagol A and B were determined to be 7-[(E)-3'-hydroxy-3',7'-dimethyl-4',6'-octadienyloxy]coumarin and 7-[(3'Z,5'E)-7'-hydroxy-3',7'-dimethyl-3',5'-octadienyloxy]coumarin, respectively.

A new glucose derivative (1) and 2-C-methyl-D-erythritol (2) were isolated from the leaves of Ferula sinaica. The two structures were elucidated by highfield NMR spectroscopy, and that of 1 was confirmed by X-ray diffraction analysis.
