摘要
The influence of cyclodextrins (CDs) on the racemization and hydrolysis of scopolamine-N-butylbromide was determined kinetically. alpha-CD and gamma-CD enhance the racemization rate of the substance. beta-CD shows no effect and DM-beta-CD (dimethyl-beta-CD) causes inhibition of racemization. The hydrolysis of the substance was retarded by beta-, gamma- and DM-beta-CD. In the presence of alpha-CD no change in hydrolysis rate was observed.
