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 ...

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...

The present study was aimed to develop the high performance thin layer chromatography (HPTLC) finger print profile of methanol and ethyl acetate extracts of leaves of Cassia fistula. Chromatographic technique was used for separation of components from different extracts of leaves. This study was planned to develop a HPTLC fingerprint profile of extracts in different solvents such as petroleum e...

BACKGROUND & OBJECTIVES Cannabis is one of the most commonly abused drugs worldwide. There is a distinct clinical correlation between cannabis abuse and mental disorders. However, it is essential to establish cannabis intake in the abusers in order to establish causality between cannabis and psychiatric illness. The limitations of current detection methods using commercial cassettes prompted us...

Conventional quantity determination of Chinese herbal medicines by High-Performance ThinLayer Chromatography (HPTLC) must be carried out on a TLC scanner for measuring the marker component on the HPTLC plate. Generally the HPTLC image of the herbal drug always takes the photograph as the permanent visual document. Considering the photo of the HPTLC image preserving all the visual quality-relate...
