title: [Study on the property of adsorption and separation of the macroporous resins for total flavonoids of Bidens bipinnata L].
abstract: OBJECTIVE
  To screen macroporous resins for isolation and purification of total flavonoids of Bidens bipinnata L. (TFB) through investigating the property of adsorption and desorption of 7 kinds of macroporous adsorption resins for TFB.
  
  
  METHODS
  The content of total flavonoids was used as the evaluating criteria, and the static and dynamic adsorption-desorption methods were adopted to compare the adsorption quantity, the rate of desorption and adsorption kinetics of different macroporous adsorption resins.
  
  
  RESULTS
  Among 7 kinds of macroporous adsorption resins, the HPD 100 resin was the best for isolating and purifying TFB.
  
  
  CONCLUSIONS
  HPD 100 possess a better adsorbability and separating property, and its property is obviously higher than any other resins.
