    초록

    Cyantraniliprole은 DuPont사에서 개발한 anthranilic diamide계 살충제로 나비목 팔랑나비과(Lepidopera), 딱정벌레목(Coleoptera), 파리목(Diptera)과 흰개미목(Isoptera)과 같은 해충에 효과가 뛰어나다. 국내의 경우 고추, 대파, 복숭아, 사과, 피망 등 15품목에 잔류허용기준(0.2~2.0 mg/kg)이 설정되어있어, 본 연구에서는 대파 중에 잔류할 수 있는 cyantraniliprole의 잔류분석시험법을 HPLC-VUD를 이용하여 개발하고자 하였다. Allium속에 포함되는 조미채소인 대파는 함유황 유기화합물을 가지고 있는 대표식물로 이를 제거하기 위한 전처리법 개발이 아주 중요하다. 이를 위해 함유황 유기화합물을 생성하는allinase 효소를 불활성화시키기 위해 pH 10의 염기상태로 만들어서 효소의 활성을 감소시켜 황화합물의생성을 감소시켰다. 확립된 시험법 검증을 위해 회수율을 측정한 결과 본 시험법의 회수율은 81.9~83.2% 로 나타났으며, 분석오차는 10% 미만으로 코덱스가이드라인에 적합하였다. Cyantraniliprole의 정량한계는 0.05 mg/kg이었으며, 추가적으로 LC-MS를 통한 재확인 과정을 확립하였다. 활용될수 있다고 생각된다.

    Abstract

    Cyantraniliprole, which is an ananthranilic diamide insecticide that was developed by the DuPont Corporation, was registered in the Republic of Korea in 2012. It offers exceptional insecticidal activity on a broad range of Lepidopera, Coleoptera, Diptera, and Isoptera. The maximum residue limits are set to pepper, peach, apple, sweet pepper, welsh onion, and so on (0.2~2.0 mg/kg). Therefore, an analytical method for determining cyantraniliprole residue in agricultural products was developed to ensure food safety. In previous studies, welsh onions were among vegetables included in the allium species, which is a representative plant with sulfur organic compounds. In this study, the analytical method was developed and evaluated for the elimination of sulfur compounds from the test solution of allium species during pesticide residue analysis. In order to inactivate the enzyme allinase and produce sulfur compounds, sample extraction was made in the base state pH 10 by reducing the activity of the enzyme. The recoveries of the developed method ranged from 81.9% to 83.2%, and the relative standard deviations were less than 10%. Therefore, based on the results, the method developed in this study is accurate and appropriate for use in cyantraniliprole determination. It will be used as the official method for managing the safety of cyantraniliprole residues in agricultural products.
