title: High-performance liquid chromatographic determination of the anthelmintic mebendazole in eel muscle tissue.
abstract: A simple high-performance liquid chromatographic method for the determination of mebendazole in eel muscle tissue was developed. It is applicable for concentrations of 10 micrograms/kg and higher. Muscle tissue was extracted with ethyl acetate, and the extract, after addition of hexane, was concentrated and cleaned up on a silica gel solid-phase extraction column. Mebendazole was eluted from the column with 3% acetic acid in methanol. The eluate, after reconstitution in the chromatographic mobile phase, was analysed on a LiChrosorb RP-8 column with acetonitrile-0.05 M ammonium phosphate buffer (pH 6.2) (3:7, v/v) as the mobile phase. Detection was performed at 311 nm. The average mebendazole recovery over the concentration range 10-5000 micrograms/kg eel muscle tissue was 72 +/- 6.4%. The calibration curve for spiked samples was linear throughout the range 10-10,000 micrograms/kg (r = 0.999).
