Enantioseparation of Penconazole, Myclobutanil and Triadimefon by Cyclodextrin-Modified Micellar Electrokinetic Chromatography

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...

Chiral 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...

Enantiomeric separation of primaquine, an anti-malarial drug, by cyclodextrin-modified micellar electrokinetic capillary chromatography.

Separation of 1,4-benzodiazepine Derivates by Cyclodextrin Modified Micellar Electrokinetic Chromatography

The electrophoretic separation of electrically neutral benzodiazepines (BZDs) can be achieved by micellar electrokinetic chromatograpy (MEKC). The cyclodextrin (CD)-modified micellar electrokinetic chromatography separation of eight of the most frequently used BZD was obtained within 15 minutes at + 25 kV on a 64.5 cm x 50 μm I.D. silica capillary at 25C, using a 25 mM sodium tetraborate-50 mM ...
