title: [Research on formulation process of Yigong capsule].
abstract: OBJECTIVE
  To choose the best supplementary material and formulation process of Yigong capsule.
  
  
  METHODS
  Critical relative humidity, absorption curve of moisture, angle of repose were used as the norms of the research. The suitable preparation and formulation process of Yigong capsule had been sieved.
  
  
  RESULTS
  It was feasible that the combined preparation of PH102 micro cellulse were mixed with the medicinal powder. The absorption of moisture of the medicinal powder was improved. The humidity of mass production and store was lower than 64%.
  
  
  CONCLUSIONS
  This craft simple is feasible and can provide the better anti-water absorbability of formulation process condition for Yigong capsule.
