title: [Kinetic study on the volatility of menthol and borneol].
abstract: OBJECTIVE
  To study the volatile regularity of menthol and borneol in granule and lozenge at different temperature.
  
  
  METHODS
  Kinetic method with GC being detection technique.
  
  
  RESULTS
  The volatility of menthol and borneol acts as a pseudo first-order reaction in open system. Under the same condition, the volatile rate of menthol and borneol in granule is four times as fast as that in lozenge, and the volatile rate of borneol is faster than that of menthol.
  
  
  CONCLUSIONS
  This study can be applied to improve the quality of lozenges containing menthol or/and borneol.
