Application of Guanidine Hcl to Improve Enantioseparation of a Model Basic Drug, Cetirizine, By Capillary Electrophoresis Using Sulfated Β-Cyclodextrin
A common approach in resolving enantiomers of chiral basic drugs by capillary electrophoresis (CE) is to use cyclodextrins (especially their anionic derivatives) as chiral selector in the acidic buffer (pH ≤ 3) in normal or reversed (carrier) mode. Then, some organic modifiers are added to the buffer solution if the resolution is not satisfactory. In case of cetirizine (CTN), applying the same ...

متن کاملAbsolute determination method using chirality for glufosinate and bialaphos by gamma-cyclodextrin modified capillary zone electrophoresis.
A novel absolute determination method using chirality without any calibration curves or comparison standards has been proposed for phosphorus-containing amino acid-type herbicides, glufosinate (D,L-GLUF) and bialaphos (BIAL). This method is based on a change in the enantiomeric ratio after the spiking of a known amount of the enantiomers with different enantiomeric ratios to a sample. D,L-GLUF ...
متن کاملSimultaneous Separation of Eight Lignans in Forsythia suspensa by β-Cyclodextrin-Modified Capillary Zone Electrophoresis.
The aim of the study was to develop an alternative capillary zone electrophoresis (CZE) for simultaneous determination of phillyrin (1), phillygenin (2), epipinoresinol-4-O-β-glucoside (3), pinoresinol-4-O-β-glucoside (4), lariciresinol (5), pinoresinol (6), isolariciresinol (7) and vladinol D (8) in Forsythia suspensa. The structural types of lignans 1-8 could be attributed to bisepoxylignans ...
متن کاملEnantioseparation of chiral sulfoxides and sulfinate esters by capillary electrophoresis.
Forty-one chiral sulfoxides and sulfinate esters were separated using sulfated beta-cyclodextrin and carboxymethyl beta-cyclodextrin as chiral selectors. Binding constants of some analytes to both chiral selectors were measured in order to examine and help explain the observed migration behavior and enantioselectivity trends. Overall, sulfated beta-cyclodextrin separated a greater number of com...
