ABSTRACT
<p><b>OBJECTIVE</b>To optimize the extraction process of root of Polygoni multflori and validate the interrelation between antioxdative capacity and the content of 2,3,4,5-tetrahydroxystilbene-2-O-beta-D-glucoside in root of P. multiflori.</p><p><b>METHOD</b>The optimum extraction was abserved with the orthogonal design; 2,3,4,5-tetrahydroxystilbene-2-O-beta-D-glucoside was determined by HPLC and the antioxidative capacity by using photochemiluminescence detection method with the Photochem supplied by Analytik Jena AG; the concentration of ethanol, amount of ethanol, extraction time and extraction times were the four factors in the extraction.</p><p><b>RESULT</b>The concentration of ethanol and extraction times had significant effect on the content of 2,3,4,5-tetrahydroxystilbene-2-O-beta-D-glucoside and the antioxidative capacity of the crude extract.</p><p><b>CONCLUSION</b>The best extraction process is to extract three times by using 10 fold EtOH(60%), refluxing at 85 degrees C and to extract one and half hours each time.</p>
