Eight new coumarin glycosides were isolated from the methanolic extrac
t of the root and rhizoma of Glehnia littoralis FR, SCHMIDT ex MIQ. (U
mbelliferae; ''hamabofu'' in Japanese). From the results of spectral i
nvestigation, they were characterized as glycosides of (S)-peucedanols
, (S)-7-O-methylpeucedanols, marmesin and hydroxyimperatorin derivativ
es, respectively.
