Abstract
A simple determination method of dinoseb and dinoterb in agricultural products, livestock products and seafood by LC-MS/MS was developed. Agricultural samples were extracted with acetone (in the case of rice, soybean and tea leaf, phosphoric acid was added). An aliquot of crude extract was partitioned with hexane and sat. sodium chloride solution. In the case of livestock products and seafood, samples were extracted with a mixture of acetone, hexane, water and sodium chloride, and the organic layer was collected. Clean-up was performed using a PSA mini column. The LC separation was performed on a C18 column with methanol–water (19 : 1) containing 0.005 v/v% acetic acid as a mobile phase, and MS with negative ion electrospray ionization was used for detection. The calibration curve was linear between 0.0005 to 0.04 μg/mL for each compound. Average recoveries (n=5) of dinoseb and dinoterb from 20 kinds of agricultural products, livestock products and seafood fortified at the MRLs were 77–111%, and the relative standard deviations were 2–15%. The limits of quantitation were 0.001 μg/g for both compounds.
