Abstract

An improved quick, easy, cheap, effective, rugged, and safe (QuEChERS) method combined with highperformance liquid chromatography (HPLC) coupled to diode array detection was established for the determination of fomesafen and quizalofop-p-ethyl in beans. It is simple and efficient and can be used in most laboratories. This method optimizes four chromatographic conditions, namely, mobile phase, mobile phase ratio, flow rate, and detection wavelength. The effects of extraction agent, extraction dose, extraction time, NaCl amount, and adsorbent on the pretreatment effect were studied. The recoveries were high (92.4–117.8%), and repeatability was good (relative standard deviation [RSD] ranged from 0.35 to 4.36%). The standard solutions ranged from 0.1 to 25 μg/mL. The detection limits of fomesafen and quizalofop-p-ethyl were 0.005 and 0.003 mg/kg, respectively.

改良QuEChERS-HPLC-DAD法测定大豆中氟沙芬和对乙酯的含量

建立了一种快速、简便、廉价、高效、可靠、安全的高效液相色谱-二极管阵列检测方法(QuEChERS)，用于测定大豆中氟沙芬和对乙基quizalofop的含量。它简单、高效，可用于大多数实验室。该方法优化了流动相、流动相比、流速和检测波长4个色谱条件。研究了萃取剂、萃取剂量、萃取时间、NaCl用量和吸附剂对预处理效果的影响。加样回收率高(92.4 ~ 117.8%)，重复性好(相对标准偏差[RSD]为0.35 ~ 4.36%)。标准溶液范围为0.1 ~ 25 μg/mL。检测限分别为0.005 mg/kg和0.003 mg/kg。

期刊介绍： ''Quality Assurance and Safety of Crops & Foods'' is an international peer-reviewed journal publishing research and review papers associated with the quality and safety of food and food sources including cereals, grains, oilseeds, fruits, root crops and animal sources. It targets both primary materials and their conversion to human foods. There is a strong focus on the development and application of new analytical tools and their potential for quality assessment, assurance, control and safety. The scope includes issues of risk assessment, traceability, authenticity, food security and socio-economic impacts. Manuscripts presenting novel data and information that are likely to significantly contribute to scientific knowledge in areas of food quality and safety will be considered. ''Quality Assurance and Safety of Crops & Foods'' provides a forum for all those working in the specialist field of food quality and safety to report on the progress and outcomes of their research.
