متن کاملAnti-amnestic activity of pseudocoptisine from Corydalis Tuber.
Pseudocoptisine, a quaternary alkaloid with benzylisoquinoline skeleton, was isolated from Corydalis Tuber, one of the important medicinal plants in traditional medicine. Pseudocoptisine inhibited acetylcholinesterase (AChE) activity in a dose-dependent manner, and the concentration required for 50% inhibition was 12.8 microM. In further study, the anti-amnesic activities of pseudocoptisine in ...
