JPC - Journal of Planar Chromatography - Modern TLC
Authors: Marcello Nicoletti, Chiara Toniolo, Francesca Gallo, Giuseppina Multari, and Giovanna Palazzino

A high-performance thin-layer chromatography (HPTLC) method was developed for simple and rapid chemical analyses of multi-ingredient botanicals. The method was based on comparison of the fingerprint of the marketed multi-ingredient botanical with the fingerprints of the extracts of its component plants and of a handmade mixture of the constituent extracts in a ratio as similar as possible to that of the market product, when labeled. Planar chromatography analysis was completed by a densitometric scansion. The analyses revealed a good correspondence between the market products and the handmade mixture of standard extracts.
