Objective To develop adetermination of triclosan and triclocarban in fruit by dispersive solid-phase extraction (DSPE) combined with high performance liquid chromatography (HPLC). Methods The analytes were supersonic extracted from the fruit samples by acetonitrile, and purified by dispersion solid phase extraction using C18 sorbent (200 mg), then analyzed by high performance liquid chromatography. The chromatographic separation was performed on a PICKERING C8 column (4.6 mm×250 mm i.d.,5 μm). The mobile phase consists of methanol-H2O (78:22 V:V) at a flow rate of 1.2 mL/min, the detector is set at 278 nm. Results The recoveries were in the range of 72.9%~104.4%, and the relative standard deviation(RSD)were2.1%~9.1%.The limit of detection were 0.05 and 0.02 mg/kg, and the limit of quantification were 0.15 and 0.06 mg/kg for triclosan and triclocarban.Conclusion This method was quick and easy, and applicable to determinate triclosan and triclocarban in fruit.
