title: [Study on adsorption of danshen water-soluble compounds with macroporous resin D301].
abstract: OBJECTIVE
  To study the adsorption and enrichment of effective compounds of danshensu, and protocatechualdehyde from Danshen water extracts by macroporous resin D301.
  
  
  METHODS
  The change of active compounds was observed by detecting the amount of danshensu and protocatechualdehyde with HPLC.
  
  
  CONCLUSIONS
  Macroporous resins D301 can be used in the process of adsorbing and purifying active compounds of danshensu and protocatechualdehyde, and increase the amount of active compounds in water extracts.
