title: [Study on quality standards of decoction pieces of salt Alpinia].
abstract: OBJECTIVE
  To establish the quality criteria for decoction pieces of salt Alpinia.
  
  
  METHODS
  Decoction pieces of salt Alpinia were measured with moisture, total ash, acid-insoluble ash, water-extract and volatile oils according to the procedures recorded in the Chinese Pharmacopoeia 2010. The content of Nootkatone was determined by HPLC, and NaCl, by chloridion electrode method.
  
  
  RESULTS
  We obtained results of total ash, acid-insoluble ash, water-extract and volatile oils of 10 batches of decoction pieces of salt Alpinia moisture; Meanwhile we set the HPLC and chloridion electrode method.
  
  
  CONCLUSIONS
  This research established a fine quality standard for decoction pieces of salt Alpinia.
