Yuvali, Donay published the artcileAn environment-friendly and rapid liquid-liquid microextraction based on new synthesized hydrophobic deep eutectic solvent for separation and preconcentration of erythrosine (E127) in biological and pharmaceutical samples, Product Details of C8H18O, the main research area is liquid microextraction hydrophobic deep eutectic solvent erythrosine; Blood; Deep eutectic solvent; Erythrosine; Liquid-liquid microextraction; Pharmaceutical samples; Urine.
A new deep eutectic solvent (DES) consist of tetrabuthylammonium bromide (TBABr) and 1-octanol at 1:2 M ratio was prepared for the first time and characterized by FTIR spectroscopy (FTIR), proton NMR (1H NMR) and carbon NMR (13C NMR) techniques. The new DES was used as an extraction solvent in the ultrasound assisted liquid-liquid microextraction (UA-LLME) of Erythrosine (E127) in blood, urine, pharmaceutical tablet and syrup samples. Accurate and sensitive determination of erythrosine was accomplished with the combination use of DES-UA-LLME and UV-visible spectrophotometric detection. Before applying UA-LLME, while protein precipitation was applied to blood samples, pharmaceutical tablets were homogenized and dissolved in methanol. The proposed DES-UA-LLME/UV-visible procedure was applied directly to urine, syrup sample and supernatant of blood and tablet samples with high recoveries in range of 90% and 100%. Erythrosine in the aqueous sample phase was extracted into 200μL hydrophobic DES phase at pH 7.0. The effect of important anal. variables such as pH of sample solution, mol ratio of DES components, volume of DES, ultrasonic-based extraction time, sample volume and salt effect were optimized. The preconcentration factor (PF), limit of detection (LOD), intra-day and inter-day relative standard deviations (relative standard deviation, %) for the developed procedure were found as 40, 3.75μg·L-1, 2.6% and 4.6%, resp.
