Abstract:
A new isoflavone glycoside, echinoside (7), together with 7-hydroxyisoflavone, kaempferol-4'-methylether, kaempferol-7-methylether, myrecetin-3-O-alpha-L-rhamnoside, kaempferol and kaempferol-3-O-alpha-L-rhamnoside, has been isolated from the whole plant of Echinops echinatus. The structure of echinoside has been established by chemical and spectral data. This is the first report of the occurrence of these flavonoids in E. echinatus.
