Enantioseparation of Penconazole, Myclobutanil and Triadimefon by Cyclodextrin-Modified Micellar Electrokinetic Chromatography
Simultaneous enantioseparation of three chiral triazole fungicides i.e. penconazole, myclobutanil and triadimefon by cyclodextrin-modified micellar electrokinetic chromatography (CD-MEKC) under acidic condition was investigated with different HP-γ-CD concentrations as chiral selector. The three triazole fungicides have an asymmetrically substituted carbon atom respectively, and they all contain...
متن کاملApplication 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 کاملChiral separation of vinpocetine using cyclodextrin-modified micellar electrokinetic chromatography.
A cyclodextrin-modified micellar electrokinetic chromatography (CD-MEKC) technique has been developed for enantioseparation of vinpocetine using an inexpensive 2-hydroxypropyl-β-CD (HP-β-CD) as the chiral selector (CS). The best chiral separation was achieved using 40 mM HP-β-CD as the CS in 50 mM phosphate buffer (pH 7.0) consisting of 40 mM sodium dodecyl sulfate (SDS) at a separation tempera...

متن کاملEnantioseparation of Ofloxacin by Ligand Exchange Capillary Electrophoresis Using L-Histidine Modified Nanoparticles as Chiral Ligand
L-histidin modifiye nanopartiküllerin kiral ligand ve Cu ’nin merkez iyon olarak kullanılması ile yeni bir kiral ligand değişim kapiler elektroforez yöntemi geliştirildi. İlk olarak, MAH ve EDMA’nın polimerizasyonu ile polimerik nanopartiküller hazırlandı. Nanopartiküller atomik kuvvet mikroskobu (AFM), FTIR ve elemental analiz ile karakterize edildi. Nanopartiküllerin elementel analizi sonucu ...
