title: [Study on HPLC fingerprint of Alpinia officinarum].
abstract: OBJECTIVE
  To establish the chromatography fingerprint of Alpinia officinarum by HPLC.
  
  
  METHODS
  An optimum HPLC conditions which were obtained under the assessment of LC-MS were as follows: Shim-pack VP-ODS column (2.0 mm x 250 mm, 5 microm), 0.1% HAc aqueous solution as phase A, 15% Acetonitrile: 40% Methanol: 45% Tetrafuran as phase B, the flow rate was 0.20 mL/min, column temperature was 35 degrees C and UV detector was set at 280 nm.
  
  
  RESULTS
  The HPLC fingerprint of Alpinia officinarum was established, the consensus 10 peaks and their relative retention times along with the ranges of relative area were determined.
  
  
  CONCLUSIONS
  The method is reliable and stable and can be used for the quality control and identification of Alpinia officinarum.
