摘要

AbstractThe simultaneous HPLC determination of clofentezine, fenoxycarb and hexythiazox in apples, pears and their pulps is described. The method is based on a clean‐up procedure carried out on a Seppak C18 cartridge followed by HPLC analysis on an RP‐18 column using acetonitrile + water as mobile phase. Average recoveries were 85.0 for clofentezine, 84.8 for fenoxycarb and 75.6 for hexythiazox on apple matrix; recoveries from pear matrix were in the same range. UV detection limits at 240 nm were 0.07 mg kg−1for clofentezine, 0.064 mg kg−1for fenoxycarb and 0.08 mg kg−1for he
