Isolation and identification of a new dicoumarin from the roots of Daphne genkwa / 药学学报

ABSTRACT

<p><b>AIM</b>To investigate the chemical constituents of the roots of Daphne genkwa.</p><p><b>METHODS</b>Silica 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.</p><p><b>RESULTS</b>A 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.</p><p><b>CONCLUSION</b>Isodaphnoretin is a new compound.</p>
