Determination of carotenes by thin-layer chromatography.
The carotenoids of yellow, red and tangerine tomato fruits were separated and identified by thin-layer chromatography (TLC). β-carotene is extracted with a mixture content hexan and acetone. The various systems of adsorbents and solvents for TLC of carote and tomato carotenes were examined, and it was revealed that the most suitable TLC system for separation and identification was silica gel pl...
متن کاملDetermination of Silver in Aluminum by Thin Layer Chromatography
Small quantities of silver in technical aluminum can be determined by TLC on the layer of microcrystalline cellulose after separation and concentration by coprecipitation with CdS. The chromatograms were developed by a solvent composed of butanol-methanol-water-nitric acid in the proportion 80 : 5 : 10 : 5 (v/v). Visualisation was made with hydrogen sulfide. After scanning the obtained spots, c...

15 صفحه اولIdentification 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 کاملChanges in Fatty Acid Composition during Preparative Thin-layer Chromatography.
n Thin-layer chromatography (TLC) is being used increasingly for the separation of the lipid classes (1, 2) prior to the analysis of their fatty acids by gas-liquid chromatography (GLC). Malins and Mangold (3) have described the separation of the methyl esters of fatty acids of menhaden oil from other lipid constituents and stated “the gas chromatogram of the total methyl ester fraction agreed ...
