Gas chromatographic determination of acrinathrine and 3-phenoxybenzaldehyde residues in honey

A procedure involving an extraction step and further gas chromatographic an alysis with flame ionization detection to determine residues of acrinathrin e and its main metabolite, 3-phenoxybenzaldehyde, in honey is proposed. Res idues can be isolated from the matrix by means of liquid-liquid extraction with a mixture of benzene-isopropanol, by solid-phase extraction with octad ecylsilane cartridges or Florisil packed columns, the latter method giving higher recoveries. Assays on spiked honey samples are carried out to test t he procedures that are afterwards applied to honey samples from treated bee hives. (C) 2000 Elsevier Science B.V. All rights reserved.
