摘要: | 目的:建立同时检测抗风湿中药制剂中非法添加的12种非甾体抗炎药。方法:采用超高效液相色谱-质谱法。色谱条件:色谱柱为Hypersil Golden C18,流动相为5 mmol/L甲酸铵溶液-甲醇(梯度洗脱),流速为0.2 mL/min,柱温为40 ℃,进样量为2 μL。质谱条件:离子源为电喷雾离子源,气帘气压为25 kPa,雾化气压为60 kPa,辅助气压为55 kPa,电喷雾电压为4 500 V,离子源温度为650 ℃,采集方式为多反应监测模式。结果:对乙酰氨基酚、乙酰水杨酸、氨基比林、美洛昔康、布洛芬、萘普生、舒林酸、尼美舒利、双氯芬酸、吲哚美辛、酮洛芬、塞来昔布检测质量浓度线性范围分别为0.01~2.0 μg/mL(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);定量限≤0.20 mg/g,检测限≤0.05 mg/g;精密度、稳定性、重复性试验的RSD<5.0%;加样回收率为80.8%~114.2%(RSD为3.85%~7.32%,n=9)。结论:该方法操作简便,精密度、稳定性、重复性好,可用于抗风湿中药制剂中非法添加的12种非甾体抗炎药的同时检测。 |
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/mL(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. |
