ABSTRACT
<p><b>OBJECTIVE</b>To optimize extracting parameters of flavonoids from Humulus lupulus.</p><p><b>METHOD</b>Based on the single factors test on ethanol concentration, material and solvent ratio, extracting temperature and extracting time, orthogonal test was performed and the best combination was confirmed.</p><p><b>RESULT</b>With the optimized technology, the maximal extracting amount of flavonoids from H. lupulus was 78 mg x g(-1).</p><p><b>CONCLUSION</b>The optimal techniques obtained are 45% ethanol extracting at 60 degrees C with material and solvent ratio 125 for 90 min.</p>
