title: New sesquiterpene coumarins from the roots of Ferula flabelliloba.
abstract: Three new sesquiterpene coumarins, namely, farnesiferone B (1), flabellilobin A (2) and flabellilobin B (3), together with nine known compounds, ligupersin A, 7-epi-gamma-eudesmol, persicasulfide A, conferdione, umbelliprenin, conferone, feselol, lehmferin and farnesiferol B were isolated from the roots of Ferula flabelliloba Rech. f. & Aell. (Apiaceae). The structures of these compounds were elucidated by various 1- and 2-D NMR techniques as well as HREIMS.
