A simple method is described for the quantitative determination of quinomethionate (6-methylquinoline- 2,3 - diyldithiocarbonate) in crops. The pesticide residue is extracted with acetonitrile and partitioned in petroleum ether. After separation from the co-extractives by thin layer chromatography (TLC), the fluorescence is measured directly on a silica gel TLC plate. An average of 89% recovery is obtained at the 0.05 ppm level in apples, peaches, pears, and tomatoes.
本文描述了一种用于定量测定农作物中喹硫磷（6-甲基喹啉-2,3-二硫代碳酸酯）的简单方法。农药残留用乙腈提取，然后在石油醚中分配。通过薄层色谱（TLC）与共提取物分离后，直接在硅胶TLC板上测量荧光。在苹果、桃子、梨和西红柿中，0.05 ppm水平下的平均回收率为89%。
