Sensitive determination of phenolic acids in extra-virgin olive oil by capillary zone electrophoresis

摘要: A sensitive, rapid, efficient, and reliable method for the separation determination of phenolic acids by capillary zone electrophoresis has been carried out. detailed optimization was out to separate 14 different compounds studying parameters such as pH, type concentration buffer, applied voltage, injection time. The performed within 16 min, using a 25 mM sodium borate buffer (pH 9.6) at kV with 8 s hydrodynamic injection. With this liquid-liquid extraction system, recovery values around 95%, it possible detect small quantities in olive oil samples. This is apparently first paper showing quantification specific family virgin
