ABSTRACT
<p><b>OBJECTIVE</b>To work out a qualitay standard of Radix Angelicae dahuricae.</p><p><b>METHOD</b>TLC and HPLC were adopted.</p><p><b>RESULT</b>Four coumerin compounds were identified by TLC, and the contents of two compounds were determined by HPLC.</p><p><b>CONCLUSION</b>Imperatorin, isoimperatorin, byakangelicin and oxypeucedaninhydrate can be found simultaneously in Radix Angelicae dahuricae. The contents of imperatorin and isoimperitorin are not lower than 0.1% and 0.04% respectively.</p>
