title: [Comparisons between NIR and HPLC fingerprint on quality stability of Shudihuang decoction pieces].
abstract: OBJECTIVE
  To establish a new method for evaluating quality stability of Shudihuang decoction pieces with near-infrared spectrum.
  
  
  METHODS
  Clustering analysis was used to distinguish different Shudihuang samples. And comparisons between NIR and HPLC fringerprint.
  
  
  RESULTS
  Results of clustering reflected the similar degree among these samples. Compared with HPLC fingerprint, NIR analytical process fast and convenient with exact results.
  
  
  CONCLUSIONS
  NIR is a feasible and effective approach to examine the quality stability of Shudihuang decoction pieces with unique virtues.
