title: [Studies on the preparation technology of beta-cyclodextrin inclusion compound for chuanxiong volatile oil extracted with CO2 supercritical fluid].
abstract: OBJECTIVE
  To explore the preparation technology of beta-cyclodextrin inclusion compound for chuanxiong volatile oil.
  
  
  METHODS
  Orthogonal test was used to evaluate the influence of the 4 factors, including the proportion of volatile oil to beta-cyclodextrin, the mode of mixing, inclusion temperature and mixing time.
  
  
  RESULTS
  The best inclusion condition is the proportion of volatile oil to beta-cyclodextrin 1:9, the mode of mixing grinding, inclusion temperature 60 degrees C and inclusion time 90 min.
  
  
  CONCLUSIONS
  The best inclusion technology of chuanxiong volatile oil is confirmed.
