High Performance Liquid Chromatographic Determination of Sodium Benzoate, Methylparaben and Propylparaben as Preservative Components in Nystatin Suspensions
A simple and sensitive method was developed for the analysis of preservatives sodium benzoate, methylparaben and propylparaben in nystatin suspensions by reversed-phase high performance liquid chromatography (HPLC), equipped with a C18 column and PDA detector. The mobile phase was a mixture of acetonitrile and acetate buffer of pH 4.4 (35:65 v/v). Under the optimized experimental conditions, se...
متن کاملDetermination of Potassium Sorbate and Sodium Benzoate in "Doogh" by HPLC and Comparison with Spectrophotometry
There are various methods for the analysis of Potassium Sorbate and Sodium Benzoate in food products, but a rapid and reliable method for identification of these preservatives in Doogh (an Iranian traditional dairy drink) is a procedure, in which high performance liquid chromatography (HPLC) utilized and followed by UV diode array detection of the two preservatives. The aim of this case study w...

متن کاملIMPROVED CHROMATOGRAPHIC METHOD FOR DETERMINATION OF SODIUM DICLOFENAC IN INJECTABLE SOLUTION AND PREDICTION OF CHEMICAL STABILITY
Two modified methods for assaying sodium diclofenac were developed by GC and HPLC. Diclofenac was converted into methyl ester derivative by methyl iodide in acetone. The ester was extract and subjected to GLC with flame ionization detector. %5 SE-30/chrom W-HP (80-100 mesh) was used as a column in GC. For reversed phase HPLC, the mobile phase was methanol and water (55-45). The separation was p...
متن کاملReproductive toxicology. Sodium saccharin.
The Toll-like receptor 4 (TLR4) is a class I transmembrane receptor expressed on the surface of immune system cells. TLR4 is activated by exposure to lipopolysaccharides derived from the outer membrane of Gram negative bacteria and forms part of the innate immune response in mammals. Like other class 1 receptors, TLR4 is activated by ligand induced dimerization, and recent studies suggest that ...
