The present study was undertaken to determine the residues of norfloxacin in muscle, liver and kidney of broiler chicken. On the basis of surveillance study, commonly used antibiotic norfloxacin was selected for quantifying the concentration in broiler chicken meat samples. The HPLC system was equipped with photodiode array and C18 hypersil column. The mobile phase consisting of 1 ml Ortho phosphoric acid (85 per cent v/v), 100 ml water HPLC grade with acitonitrile HPLC grade, 87:12 (v/v) then pH was adjusted to 2.0 with triethylamine HPLC Grade. The results indicated that out of 180 samples analysed, 3 liver samples of target stations, viz. T3, T6 and T10 were found positive for norfloxacin residues with concentrations of 2.00, 2.60 and 2.31 µg/kg, respectively. Samples collected from other target stations did not show residual concentration of norfloxacin in muscle, liver and kidney samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
