title: [Study on quality standards of decoction pieces of Indian stringbush root with sweat].
abstract: OBJECTIVE
  To study quality standards of 10 batches of Indian of stringbush root decoction pieces with sweat processing and build up the quality standard.
  
  
  METHODS
  10 batches of indian stringbush root decoction pieces with sweat were investigated with TLC. Moisture content, total ash, acid-insoluble ash and extractum were explored. The content of daphnoretin was determined by HPLC.
  
  
  RESULTS
  Indian stringbush root decoction pieces with sweat,the moisture content should not pass 14.5%, total ash should not pass 3.5%, acid-insoluble ash should not pass 1.0%, alcohol-soluble extractive should not lower than 9.0%, the content of daphnoretin should not lower than 0.2%.
  
  
  CONCLUSIONS
  Quality control quantization evaluation system of Indian stringbush root decoction pieces with sweat is establishment initial.
