title: [Comparison of dissolution properties between Ginseng micropowder and common powder].
abstract: OBJECTIVE
  To compare the dissolution properties of Ginseng micropowder and common powder in vitro and investigate the effect of micronization on dissolution of Ginseng.
  
  
  METHODS
  Five ginsenosides including Rg1, Re, Rf, Rb1, and Rb2 were determined by high performance liquid chromatography, and the dissolution curves of Ginseng micropowder and common powder were drawn.
  
  
  RESULTS
  The dissolution rates of ginsenosides from micropowder exceeded 90% within 5 min, significantly greater than that from common powder. But when the powders were packed in tea bags, the dissolution rates of ginsenosides were higher from common powder than from micropowder.
  
  
  CONCLUSIONS
  Micronization treatments can promote dissolution of ginsenosides from Ginseng.
