title: [Determination of nodakenin in Peucedanum].
abstract: OBJECTIVE
  To establish a HPLC method to determine the contents of nodakenin in Peucedanum.
  
  
  METHODS
  The determination method was achieved by RP-HPLC on an ODS column by UV detection at 334 nm; with nodakenin as external standard and H2O-CH3OH-CH3CN(75:5:20) as mobile phase.
  
  
  RESULTS
  Several samples of 6 species of Peucedanum were analyzed by this method. The contents of nodakenin ranged from 0.005%-3.090%.
  
  
  CONCLUSIONS
  Nodakenin cannot be used to control the quality of Peucedanum for pharmaceutical use, but this method is a simple and feasible way to control the quality of P. decursivum.
