title: [Detection of trenbolone residues in meat by thin layer chromatography and fluorimetry (author's transl)].
abstract: An new method for the qualitative and quantitative determination of trenbolone residues in meat, liver and kidney is described. The analytical procedure consists of the following steps: comminution of the meat sample; homogenisation with tetrahydrofurane; liquid-liquid partition first between acetonitril and hexane then between sodium hydroxide solution and petroleum ether/benzene; chromatography on a silica gel column. The detection on the TLC-plate is performed with 366 nm ultra violet light. The quantitative determination is carried out by means of a remission spectral fluorimeter directly on the plate. The detection limit in meat extracts was 5 ppb.
