ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the performance of AB-8 macroporous adsorption resin for adsorption and desorption of flavones in liquorice.</p><p><b>METHODS</b>The concentration of flavones in liquorice was determined by ultraviolet spectrophotometry, and the adsorption behavior of AB-8 macroporous adsorption resin to flavones in liquorice was examined for the adsorption capacity and the volume of solution loaded.</p><p><b>RESULTS</b>Optimal adsorption of flavones was achieved with the sample pH of 5, total flavones concentration in the solution of 0.85 mg/ml, sample flow velocity of 3 BV/h, and washing with 60% ethanol at the flow velocity of 3 BV/h.</p><p><b>CONCLUSION</b>AB-8 macroporous adsorption resin can be well applicable for enrichment of flavones in liquorice.</p>
