Several chiral medicines were separated on a new home-made β-cyclodextrins chiral stationary phase.The perphenylcarbamoylated β-cyclodextrin bonded silica CSP was prepared step by step,from synthesized and purified mono-6-p-toluenesulfonyl-β-cyclodextrin,mono-6-N-allylamino-β-cyclodextrin and mono-6-Nβ-cyclodextrin.By this CSP,baseline separation of five racemic medicines(fluoxetine,paroxetine,naproxen,propranolol and alprenolol) was realized.The optimal conditions were determined.The mobile phase was methanol-0.15%TEAA(35:65,V/V,pH=4.0) for paroxetine and naproxen,methanol-0.15%TEAA(30:70,V/V,pH=4.0) for fluoxetine,and methanol-0.15%TEAA(40:60,V/V,pH=5.0) for propranolol and alprenolol,respectively;the flowrate was 0.5 mL/min,the temperature 20 ℃,and UV-detector was used(254 nm).
