title: [Studies on quality standard of Peucedanum praeruptorum].
abstract: OBJECTIVE
  To establish a quality standard of Peucedanum praeruptorum for Chinese Pharmacopoeia (2005).
  
  
  METHODS
  The presence of (+/-)-praeruptorin A were identified and assayed by TLC and HPLC, respectively.
  
  
  RESULTS
  Linearity of marker was obtained over the range of 0.17696-0.88480 microg (r=0.9999). The average recovery rate was 99.72% (RSD=0.40%).
  
  
  CONCLUSIONS
  TLC is specific. The method of quantity is accurate, reappearance, simple, rapid, and suitable for the quality control of P. praeruptorum.
