Eight new coumarin glycosides were isolated from the methanolic extract of the root and rhizoma of Glehnia littoralis FR. SCHMIDT ex MIQ. (Umbelliferae; "hamabofu" in Japanese). From the results of spectral investigation, they were characterized as glycosides of (S)-peucedanols, (S)-7-O-methylpeucedanols, marmesin and hydroxyimperatorin derivatives, respectively.
