Abstract: ultra performance liquid chromatography-tandem mass spectrometry was used to determine the chemical components in fruit plum. The analysis conditions were as follows. The chromatographic separation was performed using a ZORBAX SB-C18 (3.0 mm×100 mm, 3.5 μm) column, and the temperature of the column was maintained at 35 ℃. The mobile phases were 0.2% formic acid (A) and acetonitrile (including 0.2% formic acid) (B), respectively, using a binary gradient elution at the flow rate of 0.2 mL/min. Results showed that sixteen chemical components were successfully determined in fruit plum, including 10 organic acids, 4 flavonoids, 5-hydroxymethylfurfural, and bitter amygdidine. The main chemical compositions of fruit plum were successfully and quickly determined in this paper and the results could provide the theoretical basis for further study of the efficacy basis and mechanism of action.
