Abstract: A high performance liquid chromatography method was developed for determining three fungicides including thiabendazole (TBZ), o-phenylphenol (OPP) and diphenyl (DP) residues in chopsticks. The residues were extracted with methanol by Soxhlet extraction, separated on Cosmosil C18 column by using a mixture of methanol and water (70:30) as the mobile phase at a flow rate of 1.0 mL/min and detected at 247 nm. The correlation coefficient and detection limit of this method were 0.999μg/mL and 0.01μg/mL, respectively. The recovery rates and relative standard deviations for TBZ, OPP and DP in a blank sample across three spike levels were 95.8%-97.1% and 1.4%-2.6%, respectively. This method proved simple, fast, highly efficient and accurate.
