摘要: 采用一种新的柱前衍生-反高效液相色谱法对15种水产品中的8种生物胺进行检测。利用C18(250 mm×4.6 mm,5 μm)色谱柱,以乙腈和水混合液进行梯度洗脱,流速为0.8 mL/min,在254 nm波长下进行生物胺含量的测定。结果表明,在1.0~100 mg/L浓度范围内,8种生物胺的分离呈现良好的线性相关(R2≥0.998),方法的检出限及定量限均低于国标方法,加标平均回收率为90%~110%,该方法操作简单,衍生物稳定,杂质少,结果准确可靠,能对鱼及鱼类制品中的生物胺进行检测。

Abstract: A new pre-column derivatization and reversed high performance liquid chromatography (RP-HPLC) was used to detect 8 biogenic amines in 15 kinds of aquatic products.,8 biogenic amines could be separated by a new precolumn derivatization method. The results showed that in the range of 1.0 to 100 mg/L, 8 biogenic amines showed a good linear correlation(R2≥0.998), the detection limit and quantitative limit of the method were lower than that of the national standard method. The average recovery rate of the added standard was 90%~110%. The method was simple to operate,derivatives are stable, few impurity, accurate and reliable results, can be used to detect biological amines in fish and dried fish products.

Key words: aquatic products, biogenic amines, high performance liquid chromatography
