AB  - An on-line preconcentration technique which coupled anion selective exhaustive 
      injection (ASEI)-sweeping technology with micellar electrokinetic chromatography 
      (MEKC) was used to analyze three glycyrrhiza flavonoids (isoliquiritigenin, 
      liquiritigenin and liquiritin) in medicine. The separation conditions were 
      optimized in conventional MEKC. The sample matrix, injection time of water and 
      injection time of sample were found to be the predominant influences on the 
      glycyrrhiza flavonoids stacking. Under optimal conditions, the detection 
      sensitivities were improved by 110, 120, 300 times for isoliquiritigenin, 
      liquiritigenin and liquiritin, respectively. The limits of detection (LODs) were 
      0.015, 0.014, 0.011 mg/L for isoliquiritigenin, liquiritigenin and liquiritin, 
      respectively. The recoveries were ranged in 90.6%-107% and relative standard 
      deviations (RSDs) were less than 4.5% (n=3). This method was successfully applied 
      for the detection of isoliquiritigenin, liquiritigenin and liquiritin in real 
      samples.
