title: [Studies on separation and purification of Rhizoma Fagopyri Dibotoryis extract by macroporous resin].
abstract: OBJECTIVE
  To establish a technical process for purification of extract of Rhizoma Fagopyri Dibotoryis.
  
  
  METHODS
  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.
  
  
  RESULTS
  D-101 resin had good separation performance and was suited to purify priceid in extract of Rhizoma Fagopyri Dibotoryis.
  
  
  CONCLUSIONS
  The process of applying macroporous resin to absorb and purity priceid in extract of Rhizoma Fagopyri Dibotoryis is feasible.
