title: [Study on enrichment process of Cornus officinalis glycosides with macroporous resin and active carbon].
abstract: OBJECTIVE
  To study the technological parameters of the enrichment purification of Cornus officinalis glycosides (COG) with macroporous resin and active carbon.
  
  
  METHODS
  COG was isolated and purified by active carbon and macroporous resin HPD100. The enrichment of COG was evaluated by HPLC method.
  
  
  RESULTS
  The optimum process was that 10 ml extract of Fructus Corni was absorbed with columns of macroporous resin and active carbon(R25 mm x H300 mm) and the columns were washed with 600 ml distilled water, then the morroniside and loganin was eluted from the macroporous resin and active carbon with ethanol.
  
  
  CONCLUSIONS
  The elutive rate of morroniside and logann was about 85% by the macroporous resin, 96% by the active carbon. So this method enriching COG from Fructus Corni is practical.
