چکیده انگلیسی
Preparation of (6-monoureido-6-monodeoxy) permethylated β-cyclodextrin bonded chiral stationary phase from permethylated 6-monoamino-6-monodeoxy-β-cyclodextrin is described. The optimized chiral stationary phase was evaluated by using HPLC separation of racemates of coumarin derivatives. Column characterization was performed by solid-state 13C, 15N, 29Si NMR using cross-polarization at the magic angle spinning. The development process was supported by CE experiments where the complex formation between cyclodextrins and warfarin was investigated. The results demonstrate good enantio-discrimination for coumarin derivatives.
