ABSTRACT
<p><b>OBJECTIVE</b>To investigatre appropriate macroporous resins and the optimal technological parameters of the purification process of tartary buckwheat total flavonoids.</p><p><b>METHOD</b>Static and dynamic adsorption-desorption methods were adopted, and evaluated for separating efficiency by macroporous resins absorption rates, desorption rates.</p><p><b>RESULT</b>The DM -2 macroporous resin had the best separating efficiency. The best absorbed condition is H2O as solvent of extracts, diameter vs height 1 10, pH 3 - 4, absorption power 3.0 mL x min(-1). The optimum adsorption condition is the volume of 50% ethanol 80 mL (approximately 5 BV (resin bed volume) as eluting solvent, pH 8, the desorption power 3.0 mL x min(-1).</p><p><b>CONCLUSION</b>This technology is simple, quick and cost-effective, which is suitable for industrialization.</p>
