摘要

建立了一种快速、简便、通用的三层萃取同时测定柠檬中6种杀菌剂的方法。该方法在丙酮萃取后，同时进行正己烷脱脂、乙腈分馏和盐析纯化。它允许制备测试溶液，而无需浓缩，转移和使用固相萃取柱纯化。结果表明，柠檬中的6种杀菌剂符合效度评估指南(日本厚生劳动省)的管理标准。因此，本方法可用于柠檬中杀菌剂的快速测定。

[Study of Rapid Simultaneous Determination of 6 Fungicides in Lemon Using Three-Layer Extraction].

A rapid, easy and versatile, simultaneous analytical method based on three-layer extraction was developed for the determination of 6 fungicides in lemon. In this method, degreasing with n-hexane, partitioning into acetonitrile, and purification by the salting-out effect were simultaneously performed after extraction with acetone. It allowed to prepare a test solution without concentrating, transferring, and purification using solid phase extraction column.As a result, 6 fungicides in lemon met the management criteria of the guideline for validity assessment (Ministry of Health, Labour and Welfare in Japan). Thus, the present method could be useful for a rapid determination of fungicides in lemon.
