Identification of Barbiturates by Thin-layer Chromatography.
in cases of overdose and identification of the actual barbiturate concerned may be impossible because of the closely similar Rf values of this group. Jackson (1960) described treatment with hot sulphuric acid before paper chromatography to distinguish between barbiturates of similar chromatographic mobility. The inert nature of the silica gel supporting medium used in thin-layer separations ena...
متن کاملBile 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...
متن کاملIdentification of some lipid peroxides by thin-layer chromatography.
Solvent systems are described which permit class separations of various peroxidized lipids by thin-layer chromatography. This procedure has proved useful in biological studies and for testing the deterioration of lipids. Proof is given that the least polar peroxides of methyl esters, glycerides, and fatty acids are monoperoxides; it is then assumed that the least polar peroxides in the other te...
متن کاملDielectric Barrier Discharge Ionization in Characterization of Organic Compounds Separated on Thin-Layer Chromatography Plates
A new method for on-spot detection and characterization of organic compounds resolved on thin layer chromatography (TLC) plates has been proposed. This method combines TLC with dielectric barrier discharge ionization (DBDI), which produces stable low-temperature plasma. At first, the compounds were separated on TLC plates and then their mass spectra were directly obtained with no additional sam...
متن کاملIdentification of volatile organic compounds of some Trichoderma species using static headspace gas chromatography-mass spectrometry
Fungi release wide spectrum of volatile organic compounds (VOCs) that belong to several chemical groups with different biochemical origins such as monoterpenes, sesquiterpenes, alcohols, aldehydes, aromatic compounds, esters, furans, ketones, sulfur and nitrogen compounds. Trichoderma species are the most studied fungal biocontrol agents and are successfully used as biofungicides and biofertili...
