| 英文摘要 | A simple and efficient hollow fiber liquid-phase microextraction (hf-lpme) technique in conjunction with high-performance liquid chromatography is presented for extraction and quantitative determination of aristolochic acid i in human urine samples. several parameters influencing the efficiency of hf-lpme were investigated and optimized, including extraction solvent, stirring rate, extraction time, ph of donor phase and acceptor phase. excellent sample clean-up was observed and good linearity with coefficient of 0.9999 was obtained in the range of 15.4-960 mu g/l. this method provided a 230-fold enrichment factor and good repeatability with relative standard deviations (rsd) lower than 6.0%. the limit of detection value for the analyte in urine samplewas 0.01 mu g/l at a signal-to-noise ratio of 3. the extraction recovery from urine samples was 61.8% with an rsd of 9.71%. copyright (c) 2010 john wiley & sons, ltd. |
