Determination of MDMA, MDEA and MDA in urine by high performance liquid chromatography with fluorescence detection.
This paper describes the development and validation of analytical methodology for the determination of the use of MDMA, MDEA and MDA in urine. After a simple liquid extraction, the analyses were carried out on a high performance liquid chromatography (HPLC) in an octadecyl column, with fluorescence detection. The mobile phase using a sodium dodecyl sulfate ion-pairing reagent allows good separa...
متن کاملHigh-Performance Liquid Chromatography Determination of Methotrexate in Plasma
This article describes a simple and fast high-performance liquid chromatography method for the determination of methotrexate (MTX) in plasma. Samples were collocted from children receiving high-dose MTX at shafa Hospital (Ahvaz University of Medical sciences, Ahvaz, iran) at various times after the end of eachinfusion. Plasma was deproteinized with trichloroacetic acid and the supernatant was i...

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 کاملSimultaneous Determination of Isoniazid, Pyrazinamide and Rifampin in Human Plasma by High-performance Liquid Chromatography and UV Detection
Therapeutic Drug Monitoring (TDM) of first-line anti-tuberculosis (TB) drugs is a decisive tool, allowing the clinician to successfully treat TB patients. The objective of the study was to develop and optimize a simple, sensitive, and reliable high-performance liquid chromatography (HPLC) method for the simultaneous determination of isoniazid (INH), pyrazinamide (PZA), and rifampin (RIF) levels...
