Originals Overpressed Layer Chromatography

Summary

The overpressured-layer chromatographic separation of neutral cannabinaids (Δ9 -tetrahydro-cannabinol, cannabidiol, cannabinol, cannabigerol and cannabichromene) has been achieved on amino HPTLC plates with dichloromethane as mobile phase. By use of bidirectional development up to 30 samples can be analysed on a 10 cm×20 cm plate within 4 min. Evaluation was performed by slit-scanning densitometry at 200 nm. System-suitability data confirm the applicability of the method.
