Abstract: A comprehensive method for detection of chlorogenic acid in toothpaste was established with liquid chromatography coupled to quadrupole/linear ion trap tandem mass spectrometry (LC-QTRAP-MS/MS).The samples were extracted under ultrasonic assistance.The separation was carried out on a Kinetex C 18 column (2.1 mm×100 mm,2.6 μm) using mobile phases of methanol-0.1% formic acid solution as eluant.A multiple reaction monitoring (MRM) in negative mode as survey scan and an enhanced production (EPI) scan as dependent scan in an information-dependent acquisition (IDA) experiment was adopted in mass spectrometry acquisition.External standard was employed for the quantification.Test results showed that content of the chlorogenic acid displays good linearity within 1.0~100 μg·L-1 vs.the peak area of the chromatogram with a correlation coefficient (r) of 0.999 6.The limit of detection for the chlorogenic acid is 10.0 μg·kg-1.The mean recoveries at the three spiked levels are 85.6%~96.6%,and the relative standard deviations are not higher than 5.8%.
