Tang, Jian published the artcileEnantioseparation tuned by solvent polarity on a β-cyclodextrin clicked chiral stationary phase, Formula: C16H14O6, the publication is Journal of Separation Science (2015), 38(18), 3137-3144, database is CAplus and MEDLINE.
The efficient enantioseparation of 26 racemates was achieved with the perphenylcarbamoylated cyclodextrin clicked chiral stationary phase by screening the optimum composition of mobile phase in HPLC. The chromatog. results indicate that both the retention and chiral resolution of racemates are closely related to the polarity of the mobile phases and the structures of analytes. The addition of alcs. can significantly tune the enantioseparation in normal-phase HPLC. The addition of methanol and the ratio of ethanol/methanol or isopropanol/methanol played a key role on the resolution of flavonoids in ternary eluent systems. The chiral separation of flavonoids with pure organic solvent as mobile phase indicates the preferential order for chiral resolution is methanol>ethanol>isopropanol>n-propanol>acetonitrile.
