  • Title: Automated multiple development thin layer chromatography for calystegines and their biosynthetic precursors.
    Author: Scholl Y, Asano N, Dräger B.
    Journal: J Chromatogr A; 2001 Sep 14; 928(2):217-24. PubMed ID: 11587340.
    Abstract:
    Automated multiple development thin layer chromatography (AMD-TLC) was used for separation of calystegines, a class of nortropane alkaloids, and of precursors of their biosynthesis. The calystegines differ in the number of hydroxyl groups at the nortropane ring system and in the substitution pattern. A combination of TLC methods allows the separation of the individual calystegines and separation of possible precursors of the biosynthesis. Solvent combination, development time, the number of development steps, the drying time between each run and the preconditioning parameters of the silica gel TLC plates were optimised. Limits of detection were evaluated for several detection reagents.
