摘要
Two anionic beta-cyclodextrins as chiral selectors were successfully applied in the enantioseparation of N-methyl duloxetine, duloxetine, and fluoxetine by countercurrent chromatography. Sulfobutyl ether-beta-cyclodextrin and carboxymethyl-beta-cyclodextrin showed opposite enantioselectivity for both duloxetine and N-methyl duloxetine enantiomers. Two biphasic solvent systems, n-hexane: 0.1 mol/L phosphate buffer pH 7.6 with 50 mmol/L of sulfobutyl ether-beta-cyclodextrin (1:1, v/v) and n-hexane: 0.1 mol/L phosphate buffer pH 7.2 with 50 mmol/L of carboxymethyl-beta-cyclodextrin (1:1, v/v), were selected for N-methyl duloxetine. Enantioseparation of duloxetine was achieved by recycling countercurrent chromatography using a solvent system composed of n-butyl acetate: 0.1 mol/L phosphate buffer pH 7.2 with 20 mmol/L of sulfobutyl ether-beta-cyclodextrin or carboxymethyl-beta-cyclodextrin (1:1, v/v). Asolvent system composed of n-hexane: n-butyl acetate: 0.1 mol/L phosphate buffer pH 7.6 containing 20 mmol/L of sulfobutyl ether-beta-cyclodextrin (6:4:10, v/v) was selected for enantioseparation of fluoxetine.
