title: [Function of getting rid of cores of Cornus officinalis Sieb. et Zucc. and studies on method of processing in producing area].
abstract: OBJECTIVE
  To gain a clear idea on function of getting fid of cores of Cornus officinalis Sieb. et Zucc. and elect a suitable processing method and technics of Crnus officinalis Sieb. et Zucc. in producing area.
  
  
  METHODS
  The contents of loganin and morroniside were determined in the cores and sarocarp of Cornus officinalis Sieb. et Zucc.; Using pathogonal method, the methods which Cornus officinalis sieb. et Zuee. were warmed or poached were isolated by determining quantitively loganin from Cornus officinalis Sieb. et Zucc. by HPLC.
  
  
  RESULTS
  There was a bit loganin and morroniside in the cores of Cornus officinalis Sieb. et Zuecc.; There were three aspects that were marked influence to extracted account of loganin which were hot temperature of poach, adding water and time of warming. The best suitable extracting technology was warmed in 60 degrees C by 10 min and then getted rid of cores.
  
  
  CONCLUSIONS
  Clearing the non-medicinal positon is the function of getting rid of cores of Cornus officinalis Sieb. et Zucc. and warming is better than poach.
