Detection of Griseofulvin and Dechlorogriseofulvin by Thin-Layer Chromatography and Gas-Liquid Chromatography

Detection of griseofulvin and dechlorogriseofulvin by thin-layer chromatography and gas-liquid chromatography.

A rapid and accurate method is described for the determination of griseofulvin and dechlorogriseofulvin extracted from Penicillium urticae with chloroform. Thinlayer chromatography was used to tentatively identify griseofulvin or dechlorogriseofulvin, or both. Two gas-liquid chromatographic systems provided additional qualitative information and simultaneous quantitation of the individual compo...

Arabidopsis thaliana Polar Glycerolipid Profiling by Thin Layer Chromatography (TLC) Coupled with Gas-Liquid Chromatography (GLC)

Biological membranes separate cells from the environment. From a single cell to multicellular plants and animals, glycerolipids, such as phosphatidylcholine or phosphatidylethanolamine, form bilayer membranes which act as both boundaries and interfaces for chemical exchange between cells and their surroundings. Unlike animals, plant cells have a special organelle for photosynthesis, the chlorop...

Identification of amino acid thiohydantoins directly by thin-layer chromatography and indirectly by gas-liquid chromatography after hydrolysis.

A method is described for the identification of amino acid thiohydantoins by two-dimensional t.l.c. An indirect method for the determination of amino acid thiohydantoins is described which, after hydrolysis, the corresponding amino acids are determined by g.l.c.

A Simple Method for the Separation of Minute Amounts of Tissue Lipids by Thin-layer Chromatography and Gas-liquid Chromatography.

Determination of clofibrate in biological fluids by thin-layer and gas-liquid chromatography.

A specific and sensitive method is described for the detection of clofibrate in biological fluids. The drug is separated from associated fatty acids by thin-layer chromatography and the methyl ester is quantified by gas-liquid chromatography. Recovery is excellent, and any small losses are corrected with an internal recovery standard. Although more time-consuming than other available techniques...
