摘要
The methanolic extract of the twigs of Celtis chinensis was found to show inhibitory activity on acetylcholinesterase (AChE), an enzyme that plays a role in the metabolic hydrolysis of ACh. Bioassay-guided fractionation of the methanolic extract resulted in the isolation of N-p-coumaroyl tyramine, as an inhibitor on AChE. This compound inhibited AChE activity in a dose-dependent manner, and the IC50 value of trans-N-p-coumaroyl tyramine was 34.5 mug/mL (122 muM).
