説明
An HPLC method for determination of iprodione and its metabolite in agricultural products was developed. The residues were extracted from vegetables and fruit with acetone or from cereal and beans with acetonitrile, and then re-extracted into ethyl acetate. The extracts were cleaned up by Florisil column chromatography. The Florisil column was washed with 50ml of 50% ether in n-hexane, and iprodione and its metabolite were eluted with 50ml of 15% acetone in n-hexane. Recoveries of iprodione and its metabolite added to samples at 0.5ppm ranged from 70.3 to 105.0% (except from tea), and the detection limits were 0.02ppm.<br>Tea gave low recoveries because iprodione and its metabolite were scarcely extracted from tea leaves with hot water. Iprodione dissolved in methanol gradually changed to its metabolite during storage at room temperature. Therefore the standard solution should be freshly prepared as occasion demands.
