title: Daphwazirin, biscoumarin glycopyranoside from Daphne oleoides.
abstract: Daphwazirin, a new biscoumarin glycoside (1), along with four known compounds (2), (3), (4) and (5) has been isolated from the roots of Daphne oleoides. Its chemical structure is established as 7-hydroxy-8-[2-oxo-2H-1-benzopyran-7'-(O-alpha-L-rhamnosyl)-6'-yl]-2H-1-benzopyran-2-one through spectroscopic techniques and chemical analysis.
