title: [Evaluation of cyclodextrin inclusion of the volatile components in compound traditional Chinese medicine].
abstract: OBJECTIVE
  To study the factors affecting cyclodextrin (CD) inclusion of the volatile components in compound traditional Chinese medicines and evaluate the stability of the inclusion compound.
  
  
  METHODS
  This study took Gengnian compound as an example to examine the factors affecting the inclusion process according to the inclusion compound utilization ratio. Orthogonal design method was employed optimize the parameters in the inclusion process. The moisture absorption rate of the beta-CD inclusion compound was determined in different humidity and Q10 was used to predict its.
  
  
  RESULTS
  The inclusion method, inclusion compound dosage, temperature, inclusion time, and the drying method could all obviously influence the inclusion process. The results of orthogonal design study showed that the optimal beta-CD inclusion of Gengnian compound volatile components could be achieved by adding 8-fold volume of beta-CD and stirring for 3 h at room temperature. Stability experiment showed that the humility did not significantly influence the inclusion compound, which can be stable for 1.26 years.
  
  
  CONCLUSIONS
  This study comprehensively examines the factors affecting the inclusion process and the stability of the inclusion compound, and provides experimental basis for application and study of the inclusion technology.
