title: [Study on preparation of beta-cyclodextrin inclusion volatile oil from Rhizoma Curcumae].
abstract: OBJECTIVE
  To study optimum inclusion process conditions for volatile oil from Rhizoma Curcumae.
  
  
  METHODS
  The study was carried out with orthogonal design. The process conditions were studied by determining the utilazision ratio of volatile oil from Rhizoma Curcumae, the oil-bearing rate and extract ratio of inclusion compound.
  
  
  RESULTS
  The optimum preparation conditions for inclusion were established as: volatile oil:beta-CD was 1:8, the inclusion temperature was at 80 degrees C and inclusion time for 3 h, ultilizasion rate of volatile oil was 86%.
  
  
  CONCLUSIONS
  The method can be used for mass production.
