【摘要】：建立了同時測定血漿中吲哚美辛和布洛芬兩種非甾體抗炎藥的HPLC測定方法。樣品采用乙腈沉淀蛋白提取后離心,上清液用氮氣吹干流動相復(fù)溶,以乙腈:20 mmol/L乙酸銨水溶液(甲酸調(diào)節(jié)p H為3.5)=85:15(V/V)進行洗脫,在ZORBAX SB-C18(4.6 mm×250 mm,5μm)色譜柱上分離,流速為1 m L/min,檢測波長220 nm,采用內(nèi)標(biāo)法定量,吲哚美辛和布洛芬互為內(nèi)標(biāo)。結(jié)果表明吲哚美辛和布洛芬在0.1~50μg/m L范圍內(nèi)呈良好的線性關(guān)系,吲哚美辛和布洛芬的檢出限(S/N=3)分別為1.3 ng和2.0 ng�；厥章试�86.3%~102.0%之間,日內(nèi)精密度RSD鄒3.4%。經(jīng)方法學(xué)驗證,該方法適用于血漿樣品中吲哚美辛和布洛芬的測定,且方法專屬性好、簡便快捷。
[Abstract]:A HPLC method for the simultaneous determination of indomethacin and ibuprofen in plasma was established. The sample was extracted with acetonitrile precipitated protein and centrifuged. The liquid was dissolved again with nitrogen blowing dry mobile phase and eluted with acetonitrile: 20 mmol/L ammonium acetate aqueous solution (adjusted pH 3.5 by formic acid) = 85:15 (V 鈮，
