The Chinese crude drug "Quiang Huo" (Umbelliferae) afforded three new coumarins, notopterol (7), notoptol (8) and anhydronotoptol (9) together with isoimperatorin (1), bergapten (2), bergaptol (3), nodakenin (4), osthenol (5), demethylfuropinnarin (6), p-hydroxyphenethyl anisate (10), phenethyl ferulate (11) and farcarindiol (12). The structures of 7-9 were established as dl-5[(2E)-5-hydroxy-3, 7-dimethyl-2, 6-octadienyloxy]psoralen, 5-[(2E, 5E)-7-hydroxy-3, 7-dimethyl-2, 5-octadienyloxy]psoralen and 5-[(2E, 5E)-3, 7-dimethyl-2, 5, 7-octatrienyloxy]psoralen, respectively.
