Determination 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 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 کاملSulfite analysis of fruits and vegetables by high-performance liquid chromatography (HPLC) with ultraviolet spectrophotometric detection.
Free and total sulfite were analyzed in acidified vegetable products, instant mashed potatoes, and dried apples. Sulfite was separated by HPLC and quantified with a UV-vis detector. Resolution from components of food samples was achieved by varying the acid concentration of the eluant solution and by appropriate choice of the analytical wavelength. The minimum detectable levels for sulfite were...
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...
متن کاملDetection of Oxytetracycline Residue in Infant Formula by High-Performance Liquid Chromatography (HPLC)
Determination of drug residues in food is of great importance due to their toxicity. Long-term exposure with low level of drug residues could be important, especially in children. Based on document study, oxytetracycline (OTC) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...
