Methods The column was ACQUITY UPLC BEHC18 (50 mm×2.1 mm, 1.7 μm), The mobile phase was acetonitrile -Ammonium acetate solution (containing 0.1% Acetic acid) with gradient elution at a flow rate of 0.3 mL/min. The ion source was electrospray ionization (ESI), Multiple-reaction monitoring (MRM) was performed to identify and quantify 10 anti-rheumatic constituents. Results 10 linear calibration curves were obtained with r ≥ 0.996 1. The recoveries were determinated at three concentration and ranged from 92.5% to 101.8%.The precision of the method was shown by RSD (n=5) ranged from 0.9% to 3.1%. The ranges of limit of detection were from 0.001 5 to 0.018 μg, and quantitation were from 0.004 5 to 0.55 μg. The illegally added chemicals were detected with 10 batches of 27 batches of samples. Conclusion The method were simple, sensitivity, accurate, and can be used to detect Anti-rheumatic constituents illegally added in Chinese traditional medicine and health products."/>
