Determination of Ivermectin Residues in Bovine Liver Samples By ELISA and HPLC with Fluorescence Detection
ABSTRACT Background and Objectives: Ivermectin is an anti-parasitic medication frequently used in many food-producing animals. This study aimed to investigate the level of ivermectin residue in liver samples collected from slaughterhouses in Qazvin Province, Iran. Methods: Overall, 88 bovine liver sam...
متن کاملDetermination of Astaxanthin in Trout by High Performance Liquid Chromatography Coupled with Visible Detection
Background: Astaxanthin is widely and naturally distributed in marine animals including, crustaceans, such as shrimp, crabs, and fish, such as salmon and trout. Methods: A total of 20 trout samples were collected from local market and were analyzed for astaxanthin via HPLC-UV. Analyte extraction was done by water, methanol, dichloromethane, and acetonitrile 4.5:85:5:45.5, v/v/v/v. Results: Desp...
متن کاملDetermination of amoxicillin residues in animal tissues by solid-phase extraction and liquid chromatography with fluorescence detection.
Trace levels of amoxicillin residues were determined in animal tissues by liquid chromatography (LC) with fluorescence detection. An improved solid-phase extraction (SPE) procedure requiring less flammable solvent (diethyl ether) was developed for sample preparation. Muscle samples of beef, pork, chicken, and tilapia were extracted with a phosphate buffer followed by the modified SPE procedure ...
متن کاملDetermination of flunixin residues in bovine muscle tissue by liquid chromatography with UV detection.
A new and sensitive liquid chromatography-ultra violet method with a detection limit of 6 ng/g (ppb) and a limit of quantification of 15 ng/g was developed for the determination of flunixin residues in bovine muscle tissue. Flunixin in homogenized animal tissue was extracted with acetonitrile after enzyme digestion. The tissue digest (extract) was then cleaned up on a solid-phase extraction car...
متن کاملDetermination of sulfonamide residues in eggs by liquid chromatography.
A method was developed for determining residual sulfonamide antibacterials such as sulfamethazine (SMZ), sulfamonomethoxine (SMM), sulfadimethoxine (SDM), and sulfaquinoxaline (SQ) in eggs using liquid chromatography with a photodiode array detector. The spiked and blank samples were cleaned up by using an Ultrafree-MC/PL centrifugal ultrafiltration unit. A Mightysil RP-4 GP column and a mobile...
