A method was developed to determine 4-hexylresorcinol in shrimp meat. The procedure is based on extraction of test portions with methanol followed by liquid chromatographic analysis of the extracts, using a reversed-phase column and fluorimetric detection (excitation: 280 nm, and emission: 310 nm). The confidence interval of the recovery in working range of 1.5-2.5 mg/kg was 81.6 +/- 0.8%. The relative standard deviation in the working range was 2.1%. Limits of quantitation and detection were 6.59 and 1.98 ng/mL extract, respectively, corresponding to 0.26 and 0.08 mg/kg in shrimp.
开发了一种测定虾肉中4-己基间苯二酚的方法。该程序基于用甲醇提取测试部分，然后对提取物进行液相色谱分析，使用反相柱和荧光检测（激发波长：280nm，发射波长：310nm）。在1.5 - 2.5mg/kg的工作范围内，回收率的置信区间为81.6±0.8%。工作范围内的相对标准偏差为2.1%。定量限和检测限分别为6.59和1.98ng/mL提取物，相当于虾肉中0.26和0.08mg/kg。
