Terpenoid coumarin glycosides ofFerula conocaula

Two new terpenoid glycoside coumarins have been isolated from the roots ofFerula conocaula Korov., and they have been named conferoside and cauferoside. On the basis of the study of chemical and spectral characteristics, their structures have been established as ferocaulinin 4′-O-β-D-glucopyranoside and cauferin 4′-O-β-D-glycopyranoside, respectively.
