Abstract
From the roots of Ferula persica Willd., four known coumarins (farnesiferol A, B, badrakemone, gummosin) and a new coumarin, farnesiferone A, have been isolated. From the aerial parts, badrakemone, farnesiferone A, and farnesiferol A were also isolated. Their structures were elucidated by spectroscopic methods.
