Four furocoumarins and two dihydrofuranocoumarin glycosides have been isolated from the benzene-soluble and butanol-soluble portions of the roots of Ostericum koreanum Kitagawa, respectively. Four furocoumarins have been determined as imperatorin, isoimperatorin, oxypeucedanin and oxypeucedanin hydrate, and two dihydrofuranocoumarin glycosides determined as marmesinin and $4'-O-{\beta}-D-glucopyranosyl-3'-hydroxymarmesin$ on the basis of spectral data and physico-chemical evidence.
