Enantiomers of monoterpenic hydrocarbons in essential oils from Juniperus communis
An investigation of the chiral and achiral composition of monoterpenic hydrocarbons in juniper oils has been undertaken. Samples were collected from different locations in Poland in two seasonsExpand
Resolution of some chiral mandelic acid derivatives into enantiomers by reversed-phase high-performance liquid chromatography via α- and β-cyclodextrin inclusion complexes
Abstract The resolution of mandelic acid derivatives (differing in the kind of functional group and in the position of its substitution in the aromatic ring) into enantiomers in a reversed-phaseExpand
Comparative study on camphor enantiomers behavior under the conditions of gas-liquid chromatography and reversed-phase high-performance liquid chromatography systems modified with alpha- and
TLDR
It has been found that beta-cyclodextrin forms complex of 1:1 stoichiometry and does not recognize enantiomers of camphor, while the enantioseparation factor alpha observed at higher concentrations of alpha-cyclodesxtrin stabilizes on the very similar value alpha+/-(GLC) approximately = alpha-/+(HPLC) about = 1.6.

Separation of some chiral flavanones by micellar electrokinetic chromatography
TLDR
MEKC appeared to be a suitable and efficient analytical tool to follow enantiomeric composition of flavanones and the suggestion that interaction of sugar moiety of glycosides with SCh micelles give rise to chiral recognition. Expand
Chiral recognition ability of alpha-cyclodextrin with regard to some monoterpenoids under gas-liquid chromatographic conditions.
TLDR
Gas-liquid chromatography was applied to investigate the mechanism of alpha-cyclodextrin (alpha-CD) complexation processes with some chiral monoterpenoids differing from each other in chemical properties and structure, and it appeared that only the second step of complexation displayed marked enantioselectivity.

Resolution of Mephenytoin and Some Chiral Barbiturates into Enantiomers by Reversed Phase High Performance Liquid Chromatography via β-Cyclodextrin Inclusion Complexes
Abstract β-Cyclodextrin as the chiral mobile phase component was used for resolution of mephenytoin and some barbiturates (antidepressant drugs) into enantiomers on LiChrosorb RP 18 column. TheExpand
Resolution of ortho, meta, and para isomers of some disubstituted benzene derivatives via .alpha.- and .beta.-cyclodextrin inclusion complexes, using reversed-phase high-performance liquid
Separatlon of varlous dlsubstltuted benzene derlvatlves on a LiChrosorb RP18 column, wlth moblle phases contalnlng aor b-cyclodextrln, was systematlcally studled. The model compounds tested wereExpand
Application of α- and β-cyclodextrin and heptakis(2,6-di-O-methyl)-β-cyclodextrin as mobile phase components for the separation of some chiral barbiturates into enantiomers by reversed-phase
Abstract Using LiChrosorb RP-18 as the stationary phase, systematic studies were performed on the changes in the capacity factors of a series of hydantoin and barbituric acid derivatives (includingExpand
