chromatotron

plural chromatotrons

1. physicalchemistryA device used in radial chromatography in which solvent is added to the center of a covered silica layered plate which spins to drive a sample outward forming sample spots of different compounds as concentric rings.

   Column chromatography SiO₂, 70–230 and 230–400 mesh and disc chromatography with a chromatotron (2 mm thickness, SiO₂ plate) were adopted.

   Sub-fraction F2.2 was purified using a chromatotron eluting with 35% EtOAc-n-hexane to give compounds 5 (57.9 mg) and 6 (30.1 mg). Sub-fraction F2.3 was further separated by chromatotron (using 40% EtOAc-n-hexane, as eluent) to give compounds 7 (42.0 mg) and 8 (11.3 mg).
