AB  - A fast and efficient on-line coupled dynamic sonication-assisted 
      extraction-liquid chromatography (DSAE-LC) method was developed for the 
      determination of phenolic acids in basil, oregano, rosemary, sage, spearmint and 
      thyme. The extraction and chromatography were coupled via a solid-phase trap 
      filled with strong anion exchange material. The relative standard deviations 
      (RSDs) for the retention times were less than 0.4% and those for the peak heights 
      less than 3% except for gallic acid (RSD 1.2% for the retention times and 11% for 
      the peak heights). Limits of detection were below approximately 3ng.
