title: [Determination of cirsilineol in Herba Artemisiae scopariae collected in autumn by HPLC].
abstract: OBJECTIVE
  To establish a quantitative method for determination of cirsilineol in Herba Artemisiae Scopariae collected in Autumn.
  
  
  METHODS
  Sample was extracted with methanol, and cleaned up with polyamide column. ODS column was used with methanol-acetonitrile-0.5% acetic acid solution (24:19:57) as mobile phase. Detection wavelength was 347 nm.
  
  
  RESULTS
  Cirsilineol in sample solution was well separated. Linearity of cirsilineol was good (r = 0.9998) in range of 0.1-0.8 microgram. The average recovery was 101.3%, RSD of repeatability was 3.04%.
  
  
  CONCLUSIONS
  This method can be used for quality control of Herba Artemisiae Scopariae collected in autumn and its preparations.
