Objective: To establish a method for identifying Fritillariae Cirrhosae Bulbus and its adulterant Fritillariae Ussuriensis Bulbus. Methods: Chemometrics techniques were used for the analysis of the sample data from determination with Q TOF MS, and characteristic ion pairs were selected as m/z 578.3→164.14 and m/z 578.3→398.31 with triple quadrupole mass spectrometry applied, respectively. Then a specific approach was developed which used Waters Acquisition UPLC CSH (75 mm×2.1 mm, 1.7 μm) as column, and with acetonitrile and 0.1% formic acid solution as the mobile phase, and a flow rate of 0.4 mL·min-1. Two ion pairs: m/z 578.3→164.14 and m/z 578.3→398.31 were detected by triple quadrupole mass spectrometer with MRM mode. Results: The validation results through 108 batches of samples indicated that the two characteristic ion pairs, m/z 578.3→164.14 and m/z 578.3→398.31, could effectively distinguish between Fritillariae Cirrhosae Bulbus and its adulterant Fritillariae Ussuriensis Bulbus. Conclusion: The method had good specificity and sensitivity, and could be used for the detection of adulterated Fritillariae Cirrhosae Bulbus with Fritillariae Ussuriensis Bulbus.
