Availability of rapid and reliable methods for detection of quality in plant raw materials and botanicals is urgently needed. The recent HPTLC instrumentation allows to obtain fingerprints useful to ascertain identity and composition. The results of direct application of HPTLC devices in selected cases, using the fingerprint approach, are here reported, considered and compared with other methods. HPTLC is proposed as an useful tool for analytical validation of the novel forms of natural products.
