  • Title: Enantioseparation of baclofen with highly sulfated beta-cyclodextrin by capillary electrophoresis with laser-induced fluorescence detection.
    Author: Kavran-Belin G, Rudaz S, Veuthey JL.
    Journal: J Sep Sci; 2005 Nov; 28(16):2187-92. PubMed ID: 16318216.
    Abstract:
    The enantioseparation of baclofen (4-amino-3-p-chlorophenylbutyric acid) was achieved by CE-LIF with highly sulfated beta-CD (HS-beta-CD) as chiral selector. Naphthalene-2,3-dicarboxaldehyde was used for the derivatization of nonfluorescent baclofen. HS-beta-CD (2%) containing 50 mM borate buffer at pH 9.5 was chosen as the optimal running electrolyte and applied to the analysis of baclofen enantiomers in human plasma. The linearity of calibration curves (R2 > or = 0.998) for R-(-) and S-(+)-baclofen was in the 0.1-2.0 microM concentration range. After a simple ACN-protein precipitation, the LOD of baclofen in plasma sample was found as low as 50 nM.
