Simultaneous determination of preservatives (benzoic acid, sorbic acid, methylparaben and propylparaben) in foodstuffs using high-performance liquid chromatography.
A reversed-phased HPLC method that allows the separation and simultaneous determination of the preservatives benzoic (BA) and sorbic acids (SA), methyl- (MP) and propylparabens (PP) is described. The separations were effected by using an initial mobile phase of methanol-acetate buffer (pH 4.4) (35:65) to elute BA, SA and MP and changing the mobile phase composition to methanol-acetate buffer (p...
متن کاملdetermination of gamma - aminobutyric acid by high-performance liquid chromatography
gamma-aminobutyric acid is the main inhibitory amino acid neurotransmitter in several areas of the brain. measurement of gamma-aminobutyric acid in the brain will help elucidate its metabolic rote and diagnostic value. the liquid chromatography (lc) system consisted of a delivery pump. male rats (150-250g) were used in this study. the brain was rapidly removed from decapitated animals. trie chr...
متن کاملSimultaneous Determination of Caffeic Acid, Ferulic Acid and Isoferulic Acid in Rabbit Plasma by High Performance Liquid Chromatography
A simple and sensitive high performance liquid chromatographic method with reverse-phase column for the simultaneous quantification of caffeic acid, ferulic acid, and isoferulic acid in rabbit plasma was developed. An ODS column (150 mm × 4.6 mm I.D., 5 μm) was used as the stationary phase and the mobile phase consisted of acetonitrile/glacial acetic acid/water (15:0.5:85, v/v, pH adjusted to 4...
متن کاملDetermination of ethylenediaminetetraacetic acid in foods by reversed-phase high-performance liquid chromatography.
A convenient HPLC method for the quantitative determination of EDTA in foods was developed. EDTA in food samples was easily extracted with water by ultrasonication. After converting to Fe(III) complex in the presence of Fe(III) ions, EDTA was separated on a reversed-phase C30 column and detected with ultraviolet detection (260 nm). Citrate and malate, which are present in many foods, also forme...
متن کاملSimultaneous determination of creatinine and uric acid in human urine by high-performance liquid chromatography.
An environmentally friendly reversed-phase HPLC method for simultaneous determination of creatinine and uric acid in human urine samples has been developed. Human urine samples were pretreated by dilution, protein precipitation, centrifugation and filtration, followed by HPLC separations using a reversed-phase C(18) column with an aqueous mobile phase of phosphate buffer. The retention loss of ...
