title: [Study on HPLC fingerprint of the triterpene acids in Poria cocos].
abstract: OBJECTIVE
  To establish a method for HPLC fingerprint determination of the triterpene acids in Poria cocos.
  
  
  METHODS
  RP-HPLC, linear gradient elution and LC/MS, etc. were used to optimize the fingerprint determination method, and identify the main peaks in the HPLC fingerprint.
  
  
  RESULTS
  A preferable method for HPLC fingerprint determination of the triterpene acids in P. cocos was established, and 9 peaks in the HPLC fingerprint were identified.
  
  
  CONCLUSIONS
  A general acquaintance of the triterpene acids in P. cocos can be obtained by using the preferable HPLC fingerprint determination method, which is useful for quality evaluation of the crud drug of P. cocos.
