Determination of tilmicosin residues in cow and sheep milk by liquid chromatography.
This method was developed and validated to detect and quantitate tilmicosin residues in cow milk over a range of 0.010-10 microg/mL, and in sheep milk over a range of 0.025-0.5 microg/mL. The procedure involves extracting the milk sample with acetonitrile and using a C18 cartridge to perform a solid-phase extraction cleanup of the extract. A reversed-phase gradient liquid chromatography method ...
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 chlorpheniramine maleate and tincture ipecac in dosage form by liquid chromatography with ultraviolet detection.
A procedure was developed and validated for measuring chlorpheniramine maleate and tincture ipecac (as emetine hydrochloride) by reversed-phase liquid chromatography with methanol-10 mM sodium heptanesulfonate (20 + 30) as the mobile phase; the pH was adjusted to 4 with acetic acid, and the flow rate was at 1.5 mL/min, with ultraviolet detection at 254 nm. Propyl paraben was used as the interna...
متن کاملDetermination of rifampin in human plasma by high-performance liquid chromatography with ultraviolet detection.
A simple, specific and sensitive high-performance liquid chromatographic (HPLC) method was developed for the determination of rifampin in human plasma. Rifampin and sulindac (internal standard) are extracted from human plasma using a C2 Bond Elut extraction column. A 100-microliter volume of 0.1 M HCl is added to the plasma before extraction to increase the retention of the compounds on the ext...
متن کاملQuantitative Determination of Pravastatin in Pharmaceutical Dosage Forms by High-Performance Liquid Chromatography with Ultraviolet Detection
A simple, sensitive and precise high-performance liquid chromatographic formulations assay for pravastatin (PVS) is described. Good chromatographic separation was achieved using a Teknokroma C8 (5 μm, 25cm × 4.6mm) column and a mobile phase consisting of 10mM ammonium acetate: methanol: triethylamine (40:60:0.17 v/v/v) while at a flow-rate of 1.0 mL min(-1). PVS was detected at 239 nm and was e...
