title: [Studies on the quality standard of xingnao tinctures].
abstract: OBJECTIVE
  To establish the method for quality control of Xingnao tinctures.
  
  
  METHODS
  The Mentholum, Flos Caryophylli and Borneoum Syntheticum in this medicine were identified by TLC method. The content of Mentholum was determined by GC. Conditions of GC were: With Naphthalene as an internal standard, packed glass column, Shimadzu 7G 2.1 mm x 3.2 m, carrier gas N2, flow rate 50 mL.min-1, column temperature. 145 degrees C, ingector and detector temperature. 180 degrees C, injection way of splitless and injection volume 3 microL.
  
  
  RESULTS
  The spots on TLC plates were clear, with no interference in the blank reference. The precision and repeatability of GC were are good respectively. The average recovery was 98.4%, RSD = 0.94%.
  
  
  CONCLUSIONS
  This method was fast, simple, accurate and suitable for quality control of Xingnao tinctures.
