Abstract For several reasons modern HPTLC is well suited for the analysis of medicinal plants. The unique possibility to document and evaluate images generated from the chromatogram as well as unsurpassed flexibility are the outstanding advantages of the method. Multiple detection in combination with digital imaging broadens the field of application significantly. Besides the traditional use for identification of herbal drugs HPTLC is also suited for semi-quantitative analyses in connection with stability tests as well as for quantitative determinations of plant constituents. The most important features of HPTLC and fields of application are outlined using the examples coneflower, lavender, schisandra, anise, chaste tree, valerian, golden seal, bearberry and St.John’s wort.
