title: [Study on the inclusion of volatile oil extracted from Herba Pogostemonis and Exocarpium citri by beta-cyclodextrin].
abstract: OBJECTIVE
  To investigate the inclusion technology conditions of volatile oil extracted from Herba Pogostemonis and Exocarpium citri in Huxin Fang granules by beta-cyclodextrin.
  
  
  METHODS
  The orthogonal design was used. The percent conversion of the oil in inclusion and the yield of inclusion complex were the indices to determine the factors containing the ratio of the oil to beta-cyclodextrin, the ratio of beta-cyclodextrin to water and the grinding time of the mixture of the oil, beta-cyclodextrin and water.
  
  
  RESULTS
  The optimum conditions for the inclusion were as follows: the ratio of the oil to beta-cyclodextrin was 1:10, the ratio of beta-cyclodextrin to water was 1:3, and the grinding time was 40 min.
  
  
  CONCLUSIONS
  The optimum conditions for the inclusion were steady and feasible.
