摘　　要：A determination method for dinotefuran residue in paddy plants, brown rice, husk, soil and paddy water was established using high performance liquid chromatography （HPLC）. The simples of brown rice, plants, and soil were extracted with acetonitrile ＋ ammonia solution, while the simple of husk was extracted with dichloromethane ＋ ammonia solution. After liquid-liquid extraction, the solutions were concentrated and set to constant volume, and then quantified by external standard method. The results showed that when the adding level ranged from 0.01 mg/kg to 1.0 mg/kg, the average recoveries of dinotefuran in rice plants, brown rice, husk, soil and water were 86.4% -99.3% ; the relative standard deviations were 0.44% -3.60%, and the minimum detectable concentration was 0. 01 mg/kg.A determination method for dinotefuran residue in paddy plants, brown rice, husk, soil and paddy water was established using high performance liquid chromatography （HPLC）.
