Simultaneous determination of 14 nutrients in vegetable oils by ultra high performance liquid chromatography-tandem mass spectrometry

) were no less than 0.9971. The average recoveries of the 14 nutrients in the vegetable oil samples ranged from 80.7% to 100.5% at three spiked levels, and the relative standard deviations (RSDs) were less than 6.0%. The limits of detection (LODs) ranged from 0.01 to 0.30 μg/g. The limits of quantification (LOQs) were in the range of 0.04-1.00 μg/g. The proposed method is sensitive, accurate, fast and stable, and is suitable for the simultaneous determination of the 14 nutrients in vegetable oil samples.
