With anhydrous sodium sulfate as dispersant , Four kinds of preservatives and bactericides in raisins were extracted by solid phase dispersion method , the C18 solid phase extraction small column was used for purification. Thiabendazole, Baytan, Folpet and Prochloraz were separated by reversed -phase high performance liquid chromatography with C18 column. The mobile phase was the mixture of acetonitrile , methanol and water (50 ∶ 10 ∶ 40,v/v) and detection wavelength was 225 nm. The linearity of regression equations were good in the range of 0.01 μg/mL-200 μg/mL, with correlation coefficients were greater than 0.999 3. Limit of detection is 2.0 ng/g-20.0 ng/g. The relative standard deviations (RSD) were less than 3.18 %. This method is suitable for the analysis of relevant preservatives and bactericides in raisins.
