| Abstract: | An effective multi-residual method for the trace analysis of Vinclozolin, Myelozolin and Chlozolinate in fruits and vegetables was developed by gas chromatography. Samples were extracted with the ethyl acetate, purified with the graphite carb, elutioned with the acetone - hexane （V： V = 1：2 ）. The extracts were analyzed using GC-ECD. The detection limits （LODs） of the method was 0.002 mg/kg, and the quantification limits （LOQs） was 0.010 mg/kg for GC-ECD. The relative standard deviations （ RSDs ） of recovery for Vinclozolin, Myclozolin and Chlozolinate were lower than 15% in 10 types of agro-produets. The repetitive determinations of recovery achieved good reproducibility for Vinclozolin, Myclozolin and Chlozolinate, and the recovery of Vinclozolin, Myclozolin and Chlozolinate ranged from 72.5% to 115.5%. The method has great potential for routine analysis of Vinclozolin, Myclozolin and Chlozolinate residue in fruits and vegetables |
