Thin-layer chromatography of bile acids*
Solvent systems suitable for thin-layer chromatographic separation of 40 different bile acids are described. The influence of substituents and chain length on the separation factors in different solvent systems has been examined.

Thin‐Layer Chromatography [PDF]
AbstractTLC is used extensively in nucleic acid chemistry to monitor the progress of chemical reactions, to assay fractions collected from a larger chromatographic separation (e.g., column chromatography), and to determine optimal conditions prior to column chromatography.

Thin-Layer Chromatography of Phospholipids [PDF]
Thin-layer chromatography (TLC) is a technique that has been routinely used for the separation and identification of lipids. Here we describe an optimized protocol for the steady state labeling, separation, and quantification of yeast phospholipids using 1-D TLC.

Antimicrobial compounds produced by Actinomadura sp. AC104 isolated from an Algerian Saharan soil [PDF]
During a search for nonpolyenic antifungal antibiotics, an actinomycete designated AC104 was isolated from a Saharan soil sample by a dilution agar plating method using a chitin – vitamins B medium supplemented with rifampicin.

Unidimensional thin-layer chromatography of phospholipids on boric acid-impregnated plates.
A unidimensional thin-layer chromatography system for the separation of phospholipids has been developed. The method employs precoated plates impregnated with boric acid and is capable of resolving eight phospholipid standards, including ...

Illegally additives determination by thin layer chromatography
To find out a simple TLC method, which could identify m-phenyenediamine and o-phenylenediamine in several colors of oxidation hair coloring products simultaneously. The colors includes black, yellow, brown and red. A small amount of the sample was placed

Spot applicator for thin-layer plates
A device that lowers a micropipet into position just above a thin-layer plate is described. Use of a self-filling pipet and foot-operated bellows allows one to apply many portions of a sample to the same point at high speed without damaging the adsorbent
