Bile Compounds: Thin-layer (planar) Chromatography

With regard to the liquid chromatographic methods described for bile acid analysis, especially with regard to their determination in biological matrices, several approaches for qualitative and quantitative determination have been described. A critical evaluation of the advantages and disadvantages of these methods results in the conclusion that there are speciRc limitations for every applicatio...

Unidimensional Thin Layer Chromatography of Salicylic Acid Derivatives on Boric Acid-Impregnated Plates in Drugs Studies

A unidimensional Thin Layer Chromatography system for the separation of salicylic acid and its derivatives (sulfosalicylic acid and Aspirin) has been developed. The separation was successfully using a solvent system of chloroform-methanol-water-ammonium hydroxide 120:75:6:2 (V/V) as mobile phase on TLC plates impregnated with boric acid. The method is based on different behavior of investigated...

Thin-Layer (Planar) Chromatography

Synthetic dyes comprise a large group of organic, organic salt and organometallic compounds which number in the thousands. Most individual dyes are assigned colour index (CI) numbers which helps to identify structure and properties as well as identity where a series of names have been used by the manufacturers for the same dye. Pigments are also listed and can be either organic or inorganic in ...
