The resolution of propranolol enantiomers has been sucessfully carried out by HPLC using two phase discrimination:γ-amino propyl silica gel coated with 15%(mass fraction) of cellulose tribenzoate(CTB) as chiral stationary phase and hexane-alcohol(V∶V=85∶15) soltuion containing 0.40 mmol/L N-benzyloxycarbonyl-S-phenyl-L-cysteine(BPC) as chiral mobile phase. The chromatiographic method with flow rate of 0.3 mL/min and UV detection at 254 nm gave a separation selectivity of 1.30 and a separation degree of ...
