title: [New method of processing on Rhei Radix Et Rhizoma and study on quality control of its processing products].
abstract: OBJECTIVE
  To establish a simple, rapid and usable new method of processing on Rhei Radix Et Rhizoma and the quality control standard on its processing products.
  
  
  METHODS
  The studies of processing on Rhei Radix Et Rhizoma were proceed using yellow rice wine as solvent, through spray, soften and dry at 60-70 degrees C. The contents of total and uncombined chrysophanol and emodin in multi-Rhei Radix Et Rhizoma and its processing products were determined by HPLC.
  
  
  RESULTS
  The new method of processing on Rhei Radix Et Rhizoma was simple, rapid and usable. The contents of uncombined chrysophanol and emodin in its processing products was 80%.
  
  
  CONCLUSIONS
  This study provides a new method of processing on Rhei Radix Et Rhizoma and quality control standard on its processing products.
