✦ Synopsis


Sequential centrifugal layer chromatography (SCLC), a new preparative planar separation technique, combines the advantages of preparative centrifugal layer chromatography (CLC) and analytical, horizontal, anticircular, and sequential thin-layer chromatography (TLC). In this on-line preparative method, solvent delivery is locally and temporally variable, which means that the mobile phase can be brought onto the plate at any desired place.

The SCLC apparatus operates in two modes: circular, with the help of centrifugal force in an inclined position, and anticircular, by means of capillary action in a horizontal position. These two operation modes can be combined and repeated as often as required, hence the separation space becomes practically unlimited. In this way the capacity and separation performance is significantly increased. lnthe present papertheapparatusand themethodaredescribed and some practical aspects are mentioned.

The new sequential centrifugal layer chromatography extends the possibilities for preparative separation of furocoumarin isomers. In the present work, isobergapten, pimpinellin, bergapten, isopimpinellin, and sphondin were isolated from a prepurified extract of Heracleum sphondylium roots using two
