農產品中腈硫醌殘留量標準檢驗方法之建立

Establishment of Standard Analytical Methods for Determination of Pesticide Residues in Crops-Tests of Dithianon

摘要


腈硫醌(Dithianon)屬於有機氮劑及雜環化合物類農藥,本研究發展出利用高效液相層析(high performance liquid chromatography, HPLC)檢驗作物中腈硫醌殘留量之方法。腈硫醌以丙酮自芒果肉、芒果皮、柑橘肉、柑橘皮、楊桃、茄子、大黃瓜中萃取出,再以氯仿抽取,經矽膠過濾層析管柱(silica cartridge)淨化後以UV 250 nm偵測之,結果添加0.15~7.5 ppm檢體濃度之平約回收率為83.0~96.2%,最低檢出量在柑橘皮中為0.02 ppm。

Methods using high performance liquid chromatography (HPLC) to determine Dithianon in crops have been developed. Dithianon was extracted from crops, using acetone; it's analysis was determined by UV 250 nm after purification. Studies, performed at 0.15~7.5 ppm fortification levels, showed recovery between 83.0~96.2%. The limit of detection of Dithianon in orange flesh tested was 0.02 ppm.
