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...
متن کاملIdentification and determination of oxytetracycline, tiamulin, lincomycin, and spectinomycin in veterinary preparations by thin-layer chromatography/densitometry.
A thin-layer chromatographic/densitometric method was developed for the identification and quantitation of oxytetracycline, tiamulin, lincomycin, and spectinomycin in veterinary preparations. Silica gel-coated thin layer chromatography plates and 2 mobile phases were used to separate these constituents. The appropriate compositions of the suitable mobile phases were established: 10% citric acid...
متن کاملElectrospun polyvinyl alcohol ultra-thin layer chromatography of amino acids.
Electrospun polyvinyl alcohol (PVA) ultrathin layer chromatographic (UTLC) plates were fabricated using in situ crosslinking electrospinning technique. The value of these ULTC plates were characterized using the separation of fluorescein isothiocyanate (FITC) labeled amino acids and the separation of amino acids followed visualization using ninhydrin. The in situ crosslinked electrospun PVA pla...
متن کاملIdentification 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...
