متن کاملHigh Performance Liquid Chromatography Determination of Sertraline in Human
An accurate and sensitive reversed-phase high-performance liquid chromatograph-ic method for determination of sertraline in human serum is described using 4-chloro-7-nitrobenzofurazan as pre-column derivatization agent. The drug and an internal standard (azithrimycin) were extracted from serum using a mixture of diethyl ether-chloroform and subjected to the pre-column derivatization with...
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...
