Liquid chromatographic determination of sarafloxacin hydrochloride residues after in feed administration to gilthead seabream [sparus aurata L.]

Abstract

In this thesis, a new high performance liquid chromatographic method with two detectors (HPLC-SFD-PDA) for the reliable identification, confirmation and quantification of sarafloxacin residues in muscle plus skin, liver, kidney and vertebra of gilthead seabream (Sparus aurata L.), has been developed. According to this method an acidified methanol tissue extract is subjected to sorbent extraction on a cation exchange cartridge. Sarafloxacin quantitative elution is done with an ammoniated methanol solution and after a partition step with n-hexane the final extract is evaporated to dryness, reconstituted in mobile phase and injected to the HPLC for fluorescence identification. The chromatographic conditions are the following: - Analytical column Zorbax SB-C18, 5 μm [250 mm x 4,6 mm] – Guard column Lichrospher RP – select b, 5 μm – Column temperature 60°C – Mobile phase 30% Acetonitrile:Methanol [3 + 2] v/v 70% Trifluoroacetic 0.1%, pH 2,15 – Flow rate 0,9 mL.min-1 – Final extract volume 1 ...
