The enantiomeric resolution of epinephrine, isoproterenol, ephedrine was studied by reversed phase HPLC. beta-CD, DM-beta-CD, TM-beta-CD were used as chiral mobile phase additives. The effects of the concentration of DM-beta-CD and the concentration of methanol on resolution of D,L-epinephrine were investigated. The results showed: D,L-epinephrine and D,L… (More)
