Studies on separation and purification of Rhizoma Fagopyri Dibotoryis extract by macroporous resin / 中国中药杂志

<p><b>OBJECTIVE</b>To establish a technical process for purification of extract of Rhizoma Fagopyri Dibotoryis.</p><p><b>METHOD</b>The static adsorption capacity and elution ratio of Mixture of proanthocyanidins tannic condensation were used as evaluation to select the best resin in 3 kinds of macroporous resin. The adsorptive characteristics and elution parameters of selected resin were studied.</p><p><b>RESULT</b>D-101 resin had good separation performance and was suited to purify priceid in extract of Rhizoma Fagopyri Dibotoryis.</p><p><b>CONCLUSION</b>The process of applying macroporous resin to absorb and purity priceid in extract of Rhizoma Fagopyri Dibotoryis is feasible.</p>
