in the developing countries of tropical regions, mycotic infections are common cause of skin diseases.the use of medicinal plants in the treatment of skin diseases including mycotic infections is an age-old practice in many parts of the world. the drugs used against dermatophytosis have several side effects, but limited efficacy. there is therefore a distinct need for discovery of new, safer an...

To establish the fingerprint profile of Lobophora variegata using high performance thin layer chromatography (HPTLC) technique. HPTLC studies were carried out using CAMAG HPTLC system equipped with Linomat V applicator; TLC scanner 3, Reprostar 3 and WIN CATS-4 software were used. HPTLC finger printing of methanolic extract of Lobophora variegata revealed 9 peaks with Rf values in the range of ...

Objective: To establish the fingerprint profile of Wedelia chinensis using thin layer chromatography (TLC) and high performance thin layer chromatography (HPTLC) technique. Methods: TLC and HPTLC studies were carried out in two different solvent systems, which showed different Rf value. Results: TLC profiling of the extract confirm about the presence of various phytochemicals. HPTLC finger prin...

Commercial precoated thin-layer chromatography (TLC) and highperformance TLC (HPTLC) plates with spherical or irregular particles have been compared on the basis of theoretical plate number (N), resolution (R), linearity, development time, and limit of sensitivity for analysis of a multicomponent analgesic tablet in the fluorescence quenching mode and analysis of a five-component dye mixture in...

background and objectives: traditional polyherbal oils are still in use in persian traditional medicine (ptm). most of these formulations are prepared via traditional procedures such as maceration of herbs in oils or evaporating aqueous herbal extracts in boiling or heating oils as the vehicle. thus, their quality control, standardization and authentication are real challenges due to the lack o...

Protein analysis using high-performance thin-layer chromatography (HPTLC) is not commonly used but can complement traditional electrophoretic and mass spectrometric approaches in a unique way. Due to various detection protocols and possibilities for hyphenation, HPTLC protein analysis is a promising alternative for e.g., investigating posttranslational modifications. This study exemplarily focu...

A high performance thin layer chromatography system (HPTLC) for the separation of vitamin B2 and B12 has been developed. The separation was successfully using a solvent system of methanol, water, ammonia 7.3.1 (V/V) as mobile phase on HPTLC plates impregnated with boric acid. The effect of other mobile phases on the separation of vitamins was also examined. The method is based on different beha...

The quality of herbal drugs is usually controlled using several tests recommended in a monograph. HPTLC is the method of choice for identification in many pharmacopoeias. If combined with a suitable reference material for comparison, HPTLC can provide information beyond identification and thus may simplify quality control. This paper describes, as a proof of concept, how HPTLC can be applied to...
