Abstract

Abstract Phenolic compounds can cause health problems in humans through the food chain. Considering that fish play an important role in human diets, we established a rapid, simple and high-throughput method for the determination of 18 phenolic compounds in fish based on a modified QuEChERS sample preparation method combined with GC-MS. The average recovery of the 18 phenolic compounds was 81.3–116% at 3 spiked levels, and the relative standard deviations, RSDr and RSDwR, were in the range of 1.1–11.3% and 1.5–12.2%, respectively. The limit of detection was 2.0–10.1 μg/kg. Satisfactory linear relationships (R 2 > 0.998) were observed for the phenolic compounds in their corresponding concentration ranges. Moreover, the established method exhibited a high sensitivity, good stability, and reliability. The development of this method has an important theoretical and practical significance for establishing standards and to control the residue levels of phenolic compounds in fish.

改良的QuEChERS净化后的气相色谱-质谱法同时检测鱼类中多种酚类化合物

酚类化合物可通过食物链对人体造成健康问题。考虑到鱼类在人类饮食中的重要作用，我们基于改良的QuEChERS制样方法结合GC-MS，建立了一种快速、简单、高通量的测定鱼类中18种酚类化合物的方法。在3个加标水平下，18种酚类化合物的平均回收率为81.3 ~ 116%，相对标准偏差(RSDr)为1.1 ~ 11.3%，RSDwR为1.5 ~ 12.2%。检出限为2.0 ~ 10.1 μg/kg。酚类化合物在相应浓度范围内呈良好的线性关系(r2 > 0.998)。该方法灵敏度高，稳定性好，可靠性好。该方法的发展对建立标准和控制鱼类中酚类化合物的残留水平具有重要的理论和实际意义。
