Abstract
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 ∼3 ng.
