Abstract
Enantiomers and diastereomers of chrysanthemic, permethrinic, and deltameth rinic pyrethroic acids were separated from each other, using positively ion izable permethyl monoamino beta -cyclodextrin (PMMA beta CD). The highest c hiral resolution value was 20.0. The optimum conditions of separation were found to be 16 mm PMMA beta CD concentration and pH 6.5, where analytes and selector were in oppositely ionized states. Selectivity of PMMA beta CD pr oved to be the best among the cyclodextrin derivatives studied.
