title: [Study on processing for Rhizoma Pinelliae Praeparatum by comprehensive evaluation of multiple mark].
abstract: OBJECTIVE
  To investigate the best processing technology of Rhizoma Pinelliae Praeparatum.
  
  
  METHODS
  L9(3(4)) orthogonal design was used with four factors: quantities of quick lime and Glycyrrhiza urallensis, processing time and temperature, the contents of Calcium oxalate crystals, Guanosine and Glycyrrhizic acid were determined by RP-HPLC, the irritation test was detected by swollen rabbits eyes with processing products.
  
  
  RESULTS
  The optimized processing technology was satisfied with some conditions as follows: the processing time was 48 hours, the processing temperature was 30 degrees C, quantities of quick lime and Glycyrrhiza uralensis were 10 g and 15 g.
  
  
  CONCLUSIONS
  The optimized processing method by orthogonal design has achieved the goal to reduce toxicity, the processing time and the processing temperature are confirmed respectively, and the processing time is significantly shortened comparing with Pharmacopoeia.
