Abstract

To develop a new anti-dementia acetylcholinesterase (AChE) inhibitor from edible mushrooms, AChE inhibitory activities were determined on water and ethanol extracts of various edible mushrooms from oriental medicine markets and agriculture markets. As a result, the 70% ethanol extract from Pholiota adiposa fruiting body had the highest AChE inhibitory activity of 30.6, and its water extract also had an AChE inhibitory activity of 23.8%. Therefore, we finally selected P. adiposa as a potent anti-dementia AChE inhibitor-containing mushroom. The AChE inhibitor of P. adiposa was maximally extracted when its fruiting body was treated with water for 3hr at $70^{\circ}C$ and 70% ethanol for 12 hr at $70^{\circ}C$, respectively.
