Synergistic effect of Korean red ginseng and var. against trimethyltin-induced cognitive impairment.

Many edible plant extracts exhibit biological activities. For example, the ethanol extract of var. () inhibits acetylcholinesterase (AChE), and red ginseng is well known for promoting health.

Erucamide from Radish Leaves Has an Inhibitory Effect Against Acetylcholinesterase and Prevents Memory Deficit Induced by Trimethyltin.

In this study, we investigated a potent acetylcholinesterase inhibitor that was isolated from radish leaf (Raphanus sativus L.) extracts. Through sequential fractionation of radish leaf extract, the active constituent was identified as cis-13-docosenamide (erucamide).

2,4-Bis(1,1-dimethylethyl)phenol from Cinnamomum loureirii Improves Cognitive Deficit, Cholinergic Dysfunction, and Oxidative Damage in TMT-Treated Mice.

We previously reported that the extract of Cinnamomum loureirii (C. loureirii) significantly inhibited acetylcholinesterase (AChE), and identified 2,4-bis(1,1-dimethylethyl)phenol (BP) from C. loureirii as a potential AChE inhibitor.
