While the amino acids, enzymes and hormones are chiral, chirality plays significant
role in the life of plants, animals, as well as the human being. Chirality of molecules is
important in various industries, such as pharmaceutical, agricultural, food, electronics, etc.
Chiral drugs may have different bioavailability, distribution, biotransformation and excretion,
as well as quantitatively and/or qualitatively different pharmacological or toxic properties.
Enantiomerically pure chiral drugs have been increasingly developed for the pharmaceutical
market due to their superiority from the viewpoints of potency and safety. This is supported
by the development of new methods for enantioselective production of the chiral compounds,
as well as by the capability of the enantioselective analytical methods to allow a detection and
quantification of minor enantiomeric impurity in the presence of another enantiomer in a large
excess. The aim of the present review is to provide a short summary of the basic principles of
chiral separations on an analytical and preparative scale. In addition, some selected applications
for analytical techniques, such as gas chromatography, supercritical fluid chromatography,
high performance liquid chromatography, capillary electrophoresis and capillary electrochromatography
for the separation of enantiomers of chiral pharmaceuticals published in the
last two years are also discussed.
