Introduction
Thin layer chromatography (TLC) is frequently used to obtain the fingerprint of a plant extract. Although the retardation factor and the response to visualisation give primary information about compound identification, the direct TLC‐mass spectrometry (MS) coupling allows a more detailed characterisation of samples.

IntroductionThin layer chromatographic fingerprints of plant raw materials and extracts for food and pharma applications often focus on phenol carbonic acids and flavonoids. The visual detection and comparison of Rf values of applied reference substances only renders limited phytochemical information. Recently, direct coupling of TLC with MALDI‐TOF MS has been successfully applied for analysis of...
