Plant drug analysis by planar chromatography.
TLDR
Optimal performance laminar chromatography and automated multiple development chromatography are relatively recent techniques of planar Chromatography that can be applied with success in plant material analysis and compare with those of thin-layer chromatography.Abstract:
Optimal performance laminar chromatography and automated multiple development chromatography are relatively recent techniques of planar chromatography that can be applied with success in plant material analysis. Therefore, these methods are used to study plant extracts and constituents belonging to different chemical classes of secondary metabolism: heterocyclic oxygen compounds (coumarins, flavonoids, and anthocyanins), alkaloids and quaternary ammonium salts, cannabinoids, essential oils, ginsenosides, and cardiac heterosides. Generally, the results obtained with these methods are good, and in most cases they compare with those of thin-layer chromatography.read more

Thin-layer chromatography: challenges and opportunities
TL;DR: It is demonstrated that thin-layer chromatography has strong potential as a surrogate chromatographic model for estimating biopartitioning properties and to convert these opportunities into practice the current state-of-the-art of the core technologies is described and the principle obstacles to progress identified.

Automated multiple development thin-layer chromatography for separation of opiate alkaloids and derivatives.
J. Pothier,Nicole Galand +1 more
TL;DR: The automated multiple development (AMD) system provided a clean separation for each of three opiates groups studied and the best results have been obtained with universal gradient: methanol 100, meethanol-dichloromethane 50/50, dichloromet hane 100, hexane 100 for opium alkaloids and with gradient A: 5%.

New planar liquid chromatographic technique: overpressured thin-layer chromatography
TL;DR: In this article, a planar liquid chromatographic technique using a pressurized ultramicro chamber (PUM chamber) has been developed, where the sorbent layer is completely covered by a membrane under external pressure, and the vapour phase above the layer is virtually eliminated.
