title: [Characteristic chromatographic profile of Paeoniae Radix and its application in quality control of crude and processed drugs of different origins and processing methods].
abstract: OBJECTIVE
  To establish a HPLC method of characteristic chromatographic profile for the quality control of Paeoniae Radix.
  
  
  METHODS
  The 67 batches of samples were analyzed on a Polaris C18-A column with a gradient elution of acetonitrile and phosphate solution (pH 3.0) at a flow rate of 1.0 mL x min(-1) and detected at 230 nm.
  
  
  RESULTS
  Nine main marker peaks were identified and semi-quantificated. By the similarity evaluation software for chromatographic fingerprint of traditional Chinese medicine (Version 2004A) and hierarchical clustering analysis, 67 batches of Paeoniae Radix were classified.
  
  
  CONCLUSIONS
  The method can be applied for quality assessment of Paeoniae Radix.
