title: [Determination of content of nodakenin in Notopterygium incisum ting from different source by HPLC].
abstract: OBJECTIVE
  To develop a method for the determination of nodakenin in N. incisum.
  
  
  METHODS
  A HPLC method was used.
  
  
  RESULTS
  Y = -9509.1 + 1912709.8X, r = 0.9998. The calibration was linear in range of 0.16-0.64 microgram. The average recovery was 99.7%, RSD 1.1%.
  
  
  CONCLUSIONS
  The method is appropriate for the determination of nodakenin.
