摘要：

The beta-cyclodextrin polymer membranes based on poly(vinyl alcohol) for enantioselective permeation of amino acids were described. The cyclodextrin membrane modified with acetic anhydride had higher permeation enantioselectivity of DL-amino acids than the unmodified membrane. The enhanced abilities were explained as a result of the additional steric hindrance effect besides inclusion. The maximum of enantiomeric excess for DL-tryptophan was 25.4% with the permeation rate of D-tryptophan being up to 1.48 x 10(-5) g . m . m(-2) . h(-1).
