The Lipophilicity Examination of Some ACE inhibitors and Hydrochlorothiazide on Cellulose in RP Thin-Layer Chromatography
In this assay, the evaluation of lipophilicity of four ACE-inhibitors and hydrochlorothiazide (HCTZ) with RP-TLC on cellulose layers was described using three binary solvent systems. The selected ACE inhibitors had sufficiently different structures which can indicate the method suitability for their lipophilicity evaluation as the model substances in comparison with HCTZ. In addition, the linea...

متن کاملDetermination 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 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...
