Simultaneous Determination of Vitamin A and E in Infant Formula by Rapid Extraction and HPLC with Photodiode Array Detection
Rapid and simple method was developed for simultaneous determination of vitamins A and E contents in infant formula. Vitamins A and E were extracted by PDA-HPLC with reversed phase column using organic solvent, and their contents in Certified Reference Material (CRM) and infant formula were determined and compared with results of Food Standards Codex and AOAC method for evaluation of developed ...
متن کاملSimultaneous Determination of Caffeine and Water-Soluble Vitamins in Energy Drinks by HPLC with Photodiode Array and Fluorescence Detection
The high-performance liquid chromatography (HPLC) method with photodiode array (PDA) and fluorescence (FL) detection for the simultaneous separation and determination of caffeine and water-soluble vitamins is described. The method is relatively rapid: 13 compounds can be analyzed within 30 min: caffeine; ascorbic acid (vitamin C); thiamine (vitamin B1); riboflavin 5-phosphate (FMN, flavin monon...
متن کاملhydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
Analysis of plasma amino acids by HPLC with photodiode array and fluorescence detection.
BACKGROUND Plasma amino acids are usually analyzed by ion-exchange chromatography (IEC), a reproducible but time consuming method. Here, we test whether plasma amino acids can be analyzed using reverse-phase high performance liquid chromatography (HPLC). METHODS Filtered plasma, with S-carboxymethyl-l-cysteine as the internal standard, was derivatized and analyzed by an Agilent 1100 HPLC syst...
متن کاملDetermination of phenols in wines by liquid chromatography with photodiode array and fluorescence detection.
A reversed-phase LC method, optimised for the separation of trans- and cis-resveratrol, catechin, epicatechin, quercetin and rutin, is reported. Analyses were performed on a reversed-phase column by gradient elution. Detection was carried out by photodiode array, although the use of a fluorimetric detector considerably lowered the detection limits for catechin, epicatechin and both resveratrol ...
