Abstract:
AIMTo investigate the chemical constituents of the roots of Daphne genkwa.
METHODSSilica gel and Sephadex LH-20 column chromatographic techniques were employed for the isolation and purification. The structure was elucidated by a combination of spectroscopic analyses.
RESULTSA new dicoumarin named isodaphnoretin was isolated and the structure was established as 7-hydroxy-6-methoxy-4-[(2-oxo-2H-1-benzopyran-7-yl)-oxyl]-2H-1-benzopyran-2-one.
CONCLUSIONIsodaphnoretin is a new compound.
