| 摘 要： | 采用固相分散萃取-高效液相色谱法测定番茄酱中的2-萘酚。无水硫酸钠作分散剂、乙腈作萃取剂,考察了2,4-二氯苯氧乙酸存在时的干扰情况。色谱条件:TOSOHC18色谱柱;甲醇-水(体积比50∶50)为流动相;流速:1.0 mL/min;检测波长:230 nm。2-萘酚在0.005μg/mL～2.00μg/mL范围内线性良好,方法检出限为1μg/g,平均回收率为75.0%,相对标准偏差为3.0%。

| Abstract: | The method of solid phase dispersive extraction-high performance liquid chromatography（HPLC） was established for the determination of 2-naphthol in tomato catchup.Anhydrous sodium sulfate was used as dispersant and acetonitrile as extractive agent.In the meantime,the interference of 2,4-dichlorophenoxyacetic acid was considered in the process of analyzing.The two components were separated by TOSOHC18 column at the wavelength of 230 nm.The mobile phase was the mixture of methanol and water（50∶50,V/V） with the flow rate of 1.0 mL /min.The linear range of 2-naphthol was 0.005 μg /mL ～2.00 μg /mL with correlation coefficient of 0.999 5.The determination limit,average recovery and relative standard deviation were 1 μg /g,82.5% and 3.0% respectively. |
