Abstract
Abstract
An existing liquid chromatographic (LC) methodfor determination of thiabendazole (TBZ) residues inor on whole green bananas and potatoes was applied to whole, unwashed citrus fruits. The method is applicable for determining TBZ residues in whole oranges,grapefruits, tangerines, and lemons. TBZ is extracted from citrus homogenate with ethyl acetate, and theextract is cleaned up on a cation-exchange, solid-phase extraction column. The purified extract is analyzed by LC with a cation-ex change column and fluorescence detection. Average recovery of TBZ from whole citrus fruits fortified with TBZ at 0.05-20 ppm was 96%. The assay provides a simple, rapid, and sensitive method for monitoring TBZ residues in whole citrus fruit.
