Abstract:

The chrysin (ChR) in propolis toothpaste was extracted by methanol, purified by freezing centrifugation, separated by Diamonsil C18 column (4.6 mm×250 mm, 5 μm) and detected by mass spectrometry. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was established to determine the content of ChR in propolis toothpaste. The results show that ChR has a good linear relationship in the range of 5.0-100.0 μg/L mass concentration, and the correlation coefficients (R 2) was 0.999 8. The detection limit is 1.5 μg/kg and the limit of quantification is 5.0 μg/kg. The average recovery of the spiked standard is 93.0% to 100.1%, and the relative standard deviation (RSD) is 1.3% to 3.4%.

Key words: propolis toothpaste, chrysin, propolis extract, liquid chromatography-tandem mass spectrometry
