Abstract:
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 1μL. The ionization mode was electrospray ion source(ESI):spray needle voltage of 5500 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 en-hanced 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.
