Abstract:
OBJECTIVE:To develop a method for simultaneous determination of 12 nonsteroidal anti-inflammatory drugs (NSAIDs) illegally added into antirheumatic TCM preparations.METHODS:UPLC-MS/MS was adopted.The determination was performed on Hypersil Golden C18 column with mobile phase consisted of 5 mmol/L ammonium formate solution-methanol (gradient elution) at the flow rate of 0.2 mL/min.The column temperature was 40 ℃,and the sample size was 2 μL.A tandem quadrupole mass spectrometer equipped with electrospray ionization source was used in positive-negative ion mode:curtain gas of 25 kPa,atomizing gas of 60 kPa,auxiliary gas of 55 kPa,electrospray voltage of 4 500 V,ion source temperature of 650 ℃.The multiple reaction monitoring mode was performed.RESULTS:The linear ranges of acetaminophen,acetylsalicylic acid,aminopyrine,meloxicam,ibuprofen,naproxen,lam acid,nimesulide,diclofenac,indomethacin,ketoprofen and celecoxib were 0.01-2.0 μg/ rnL (r=0.995 6),0.05-5.0 μg/mL (r=0.997 6),0.01-2.0 μg/mL (r =0.998 7),0.02-5.0 μg/mL (r=0.995 0),0.02-5.0 μg/mL (r =0.995 3),0.02-5.0 μg/mL(r=0.996 5),0.05-5.0 μg/mL(r=0.995 4),0.02-5.0 μg/mL(r=0.996 0),0.05-5.0 μg/mL(r=0.995 9),0.02-5.0 μg/mL(r=0.995 7),0.02-5.0 μg/mL(r=0.996 8),0.01-2.0 μg/mL(r=0.998 7),respectively.The limits of quantitation were no more than 0.20 mg/g,and the limits of detection were no more than 0.05 mg/g.RSDs of precision,stability and reproducibility tests were all lower than 5.0％.The recoveries were 80.8％-114.2％ (RSD was 3.85％-7.32％,n=9).CONCLUSIONS:The established method is simple,accurate,stable and reproducible,and can be used for simultaneous determination of 12 NSAIDs illegally added into antirheumatic TCM preparations.
