Abstract

Abstract:

Objective: To develop a stable and reliable method of ultra performance liquid chromatography-tantem mass pectrometry (UPLC-TMS) for determining tertiary butyhydroquinone (TBHQ) content in edible oils. Methods: TBHQ in amples was extracted with acetonitrile, eluted by the mobile phase of acetonitrile-water with reserved C18 column as the separation olumn, scanned by negative ion detection mode with electrospray ionization as joint, detected by selected reaction monitoring SRM) mode and calibrated by external standard. Result: The detection limit of TBHQ is 0.10 mg/kg, the correlation coefficient f linear calibration curve is over 0.999 in the range of 0.05 to 2.5 μg/ml, and the recovery rate is 83% to 115%. Conclusion: The ethod is of high sensitivity, low detection limit, good determination capacity and short analysis time, and can be used to ccurately determine TBHQ content in edible oil.

Key words: ultra performance liquid chromatography-tantem mass spectrometry (UPLC-TMS), elected reaction monitoring SRM) mode, tertiary butyhydroquinone (TBHQ), edible oil
