Abstract
Differences in selectivity of several reversed phases are described by temperature-dependant HPLC-analyses of Chelidonium alkaloids. Structu ral features of the chromatographically active surfaces of Nucleosil 1 00 AB and LiChrospher 60 RP-select B are elucidated by Si-29- and C-13 -CP-MAS NMR spetroscopy and are discussed in respect to their chromato graphic behaviour.
