title: [Study on the preparation process of inclusion complex of volatile oil of Dalbergia odorifera-beta-cyclodextrin].
abstract: OBJECTIVE
  To study the optimum preparation process of the volatile oil of Dalbergia odorifera-beta-cyclodextrin.
  
  
  METHODS
  The saturated water solution mixing method was compared with microwave method and ultrasonic method by determining the ultilization ratio of the volatile oil in Dalbergia odorifera. The optimum preparation conditions were investigated by the orthogonal design. The quality of the volatile oil before and after included were analyzed by TLC.
  
  
  RESULTS
  The optimum preparation conditions for inclusion were as follows: m(volatile oil of Dalbergia odorifera): m (beta-CD) = 1:10 (g/g), ultrasonic time was 1h, the temperature was 70 degrees C. The ultilization ratio of the volatile oil was 82.02%.
  
  
  CONCLUSIONS
  Ultrasonic method is the best method.
