摘要: 建立香肠中红色2G色素的高效液相色谱法(HPLC)测定和确证的超高压液相色谱-质谱/质谱法(UPLC-MS/MS)。以0.662mol/L氨水为提取液,样品均质提取两次,离心后用C18柱净化,采用高效液相色谱-二极管阵列检测器(HPLC-DAD)检测,流动相为乙酸-乙酸铵缓冲液-甲醇(55:45,V/V),等度洗脱,流速为1mL/min,检测波长为530nm,阳性结果用UPLC-MS/MS确证。HPLC-DAD法在0.0212~1.06mg/L范围内,红色2G的峰面积与其相应浓度呈现良好相关性,r>0.999,方法测定限为0.106mg/kg,在空白样品中添加已知浓度的红色2G色素,平均回收率在79.0%~86.5%之间,相对标准偏差(RSD)在3.19%~5.06%之间。UPLC-MS/MS法的测定限为0.005mg/kg,平均回收率在75.5%~80.2%之间,RSD在3.62%~9.97%之间。该方法可用于香肠中红色2G的检测及确证。

Abstract: A high-performance liquid chromatography method (HPLC) was developed for the determination of red 2G in sausage. Sausage samples were extracted twice with 0.662 mol/L NH3 ·H2O and the extract was cleaned up on a C18 column. Red 2G was analyzed by HPLC with diode array detector and confirmed by UPLC-MS/MS. The limit of quantification (LOQ) of HPLC was 0.106 mg/kg and the average recoveries ranged from 79.0% to 86.5% with RSD values between 3.19% and 5.06%. The LOQ of UPLC-MS/MS was 0.005 mg/kg and the average recoveries ranged from 75.5% to 80.2% with RSD values between 3.62% and 9.97%. The developed HPLC method and UPLC-MS method can be applied for the determination and confirmation of red 2G in sausage.
