title: [Study of hydroscopicity of Glycyrrhiza uralensis Fisch].
abstract: OBJECTIVE
  To study hydroscopicity of Glycyrrhiza uralensis Fisch and screen the best compounding of adjuvant, and measure critical relative humidity of the best anagraph for providing reasonable relative humidity of production.
  
  
  METHODS
  Different adjuvant were adopecd and compared hydroscopicity of Glycyrrhiza uralensis Fisch at 25 degrees C and different relative humidity.
  
  
  RESULTS
  The best prescription was Glycyrrhiza uralensis Fisch: lactose: microcrystalline cellulose = 1: 0. 5: 0. 5. The critical relative humidity of prescription was 60%.
  
  
  CONCLUSIONS
  The sduty can solve the problem of mositure absorption and agglomeration in production.
