A simple and rapid isocratic HPLC assay is presented for the analysis and quantification of @entity199 , i.e., @entity23919 , @entity12263 , @entity70171 , @entity4111 and @entity70172 in the diet of laboratory animals. The @entity199 were extracted from the diet using 90% @entity1042 in water. The analysis for the @entity199 was performed by HPLC using a Whatman PartiSphere C18 column with UV detection. The mobile phase was isocratic @entity1042 -water (72:28, v/v) for @entity23919 , @entity12263 , @entity70171 and @entity4111 and @entity1042 -water (65:35, v/v) for @entity70172 . The method was simple with good repeatability (R.S.D. = 4.2-16.1%), reproducibility (R.S.D. = 3.7-19%), and accuracy (R.S.D. = 5.5-23.3%). The detection limit of the @entity199 extracted from the diet was 2 micrograms/g for @entity23919 , @entity70171 and @entity70172 , 20 micrograms/g for @entity4111 and 100 micrograms/g for @entity12263 . Excellent resolution was achieved between the @entity199 and the constituents of the diet. The method demonstrated applicability to monitoring the formulation of @entity199 in the diet of laboratory animals.
