title: [Study on preparation of beta-cyclodextrin inclusion compound of volatile oil from Aucklandia lappa].
abstract: OBJECTIVE
  To study optimum inclusion process conditions for volatile oil from Aucklandia lappa.
  
  
  METHODS
  The study was carried out with orthogonal design. The process conditions were studied by determining the utilization ratio of volatile oil from Aucklandia lappa, the oil-bearing rate and extract ratio of inclusion compound.
  
  
  RESULTS
  The optimum preparation conditions for inclusion were established as: oil: beta-CD was 1:8, the inclusion temperature and time were at 40 degrees C and for 1 h respectively, the utilization ratio of oil is 87.1%.
  
  
  CONCLUSIONS
  The method can be used for production of beta-CD on a large scale.
