Abstract - Chloramphenicol (CAP) residues were determined in 35 samples of royal jelly. Fourteen samples were collected by Veterinary Border Inspection officials in Milan and Turin and 21 were submitted by private importers to confirm the quality of their product. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for the identification and determination of CAP, according to the isotope dilution approach for the analysis of royal jelly. The presence of chloramphenicol was detected in 29 out of 35 tested samples at concentrations ranging from 0.6 $\mu$g/kg to 28 $\mu$g/kg, with an average content of 6.1 $\mu$g/kg.


Key words: royal jelly / chloramphenicol / residue / antibiotics / liquid chromatography-tandem mass spectrometry

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
