A combinative method using overpressured layer chromatography (OPLC) and TLC bioautography against O2(•-) was developed to separate antioxidants from Glehnia littoralis roots. Through target-directed isolation by the TLC bioautographic method, seven compounds including five antioxidants were rapidly isolated by OPLC and identified as 1-linoloyl-3-palmitoylglycerol, facarindiol, panaxynol, isoimperatorin, β-sitosterol, scopoletin, and umbelliferone from G. littoralis roots. This OPLC method is a very suitable separation technique for light-sensitive polyacetylenes (panaxynol and facarindiol) with higher isolated yields compared to conventional open column chromatography. This is the first report on the separation of polyacetylenes by OPLC.

Planar chromatography (PLC) is gaining importance in the analysis of natural products. Sophisticated instrumentation has become available in this field. Major progress in planar chromatography has been achieved through the development of forced-flow techniques. Progress has also been made in the capillary-controlled flow techniques with the use of modified development chambers. A large variety of stationary phases is available and strategies to optimize mobile phase compositions in PLC have been developed. The detection and quantitation in PLC has improved through direct coupling of PLC with spectroscopic methods with and the use of modern, computerized scanning densitometers.
