OBJECTIVE: To establish a rapid determination method for 9 kinds of glucocorticoid and 8 kinds of non-steroidal anti-inflammatory drugs illegally added into anti-rheumatic TCM patches. METHODS: UPLC-MS/MS method was adopted. The samples were separated on Acquity UPLC® BEN C18 column with methanol-water (90 ∶ 10,V/V) as mobile phase at flow rate 0.4 mL/min. The column temperature was set at 30 ℃, and sample size was 1 μL. The ionization mode was electrospray ion source (ESI): spray needle voltage of 5 500 V, ion source spray GS1, GS2 pressure of 50, 50 psi, ion source temperature of 500 ℃, scanning range of m/z 50-500. The multiple reaction monitoring(MRM)combined with information-dependent acquisition (IDA) and enhanced product ion scanning (EPI) was used to rapid qualitative analysis. RESULTS: The detection limits for 17 kinds of chemical components were not more than 0.400 μg/mL. RSDs for precision, repeatability, stability tests were not more than 4.93%,7.69%,9.57%, respectively. Diclofenac sodium was detected in the sample. CONCLUSIONS: The method is selective and sensitive. It is suitable for qualitative analysis of chemicals illegally added into anti-rheumatism TCM patches.
