Concerning the functional effect, most of the phenolic compounds isolated from hempseed have been shown to have high radical scavenging activity compared to quercetin, and, in addition, the phenolic amide N-trans-feryoryltyramine and especially, the lignanamides 3,3′-demethyl-grossamide and 3,3′-demethylheliotropamide were also able to in vitro inhibit the acetylcholinesterase (AChE) enzyme at a concentration of 100 μg/mL, thus exhibiting properties similar to the medicines used for the treatment of mild to moderate Alzheimer’s disease (AD) such as galanthamine [103]. This evidence concerns the gene ACHE and Alzheimer disease.
