Plant Drug Analysis by Planar 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.

Bioprospecting the Antibiofilm and Antimicrobial Activity of Soil and Insect Gut Bacteria

“…Detection was carried out using different reagents and methods, such as Fast Blue B Salt, Draggendorff, Ehrlich, Van Urk’s, Kedde’s, and Natural Products II reagents for polyphenols, alkaloids, indoles, lactones, cardenolides, and phenols and phenolic acids, respectively. As general detection reagents, copper sulfate reagent/heat and UV detection at 254 and 356 nm were used [ 43 , 44 , 45 ].…”

Chromatographic and electrophoretic methods for pharmaceutically active compounds in Rhododendron dauricum

“…TLC continues to be widely used for the standardization of plant materials used as traditional medicines [50], because it is suitable for the analysis of complex and dirty samples with poor detection characteristics, for stability and content uniformity testing. The Chinese Pharmacopoeia (1977 version) recommended TLC to identify R. dauricum L. and farrerol as a marker substance to evaluate the quality.…”
