title: [Influence of different technique process and prescription on dampproof performance of pharmaceutical materials of traditional Chinese medicine].
abstract: OBJECTIVE
  To study the influence of different technique process and prescription on hygroscopic property of pharmaceutical materials of traditional Chinese medecine (TCM) was studied.
  
  
  METHODS
  The sample prepared with banlangen and different excipients had been put in certain suroundings for 24 hours, then the hygroscopic curves and their parameters of hydroscopicity were gotten; the influence of that on hygscopic property of banlangen was studied.
  
  
  RESULTS
  The optimized damp-proof materials was polyoxylate II. The damp-proof effect enhanced with the increase of temperature and the excipient the decrease of and concentration of ethanol.
  
  
  CONCLUSIONS
  Excipients have different effect on hyproscopic property of banlangen, and the damp-proof technology has direct effect on it.
