title: [Quantitative analysis of pulegone in Herba Schizonepetae].
abstract: OBJECTIVE
  To establish the determination method of pulegone in Herba Schizonepetae.
  
  
  METHODS
  HPLC method was developed for the determination of pulegone in Herba Schizonepetae. The separation was performed on C18 column with MeOH-H2O (80:20) as a mobile phase. The detection wavelength was set at 252 nm.
  
  
  RESULTS
  The quantitation of pulegone in Herba Schizonepetae varied from 0.2-0.7 mg x g(-1). The average recovery is 96.2%, RSD 0.81%.
  
  
  CONCLUSIONS
  The method is simple, rapid and accurate.
