Beni et al." reported that three vinca alkaloid enantiomers, i.e., vincamine, vinpocetine, and vincadifformine, were separated in aqueous CE using native, neutral, and anionic CDs. The native CDs were a-CD, p-CD, and y-CD the neutral hydroxypropyl-a-CD (HP-a-CD), HP- -CD, HP-y-CD, methyl-a-CD (Me-a-CD), Me- -CD, and Me-y-CD and the anionic carboxymethyl-a-CD (CM-a-CD), CM-P-CD, CM-y-CD, sulfobutylether-p-CD (SBE- -CD), and SBE-y-CD. Uncoated fused-sUica capillaries (33.5/25 cm total length/effective length) with an i.d. of 50 p,m were used in combination with a BGE consisting of 15 mM NaOH adjusted to pH 2.5 with 10 % (w/w) aqueous H3PO4 CDs were added to this BGE in concentrations...
