摘  要：
研究建立了甲壳类水产品中4-己基间苯二酚(4-hexylresorcinol,4-HR)残留量的固相萃取-气相色谱-质谱检测方法。样品采用乙酸乙酯提取,硅胶柱净化,乙酸乙酯洗脱,气相色谱-质谱测定,外标法定量。4-HR的响应值与其质量浓度在0.05~10μg/m L范围内的线性关系良好,相关系数为0.9 997;0.05~1 mg/kg添加浓度的日内和日间平均回收率为76.8%~102%,相对标准偏差为2.43%~7.65%;检出限为0.01 mg/kg,最低定量限为0.05 mg/kg。该方法适用于甲壳类水产品中4-HR残留的检测。

摘  要：
Gas chromatography- mass spectrometry( GC- MS) coupled with solid- phase extraction was developed for determination of 4- hexylresorcinol residue in crustacean. The 4- HR was extracted with ethyl acetate,purified by silicagel column and eluted with ethyl acetate,the eluent was concentrated and dissolved in ethyl acetate- n- hexane( 1 ∶ 1,v / v),then analyzed by gas chromatography- mass spectrometry. The results showed that the linear range was 0. 05 ~ 10 μg / m L and its correlation coefficient was 0. 9 997. When spiked within 0. 05 ~ 1 mg / kg,the average recoveries of intraday and intraday were 76. 8% ~ 102%,and their relative standard deviations were 2. 43% ~ 7. 65%. The limits of detection and limits of quantitation were 0. 01 mg / kg and 0. 05 mg / kg,respectively. This method can be applied to determine the 4- HR residues in crustacea with the advantages of high extraction efficiency,high purification effect and less solvent consumption.
