“Hempseed is known for its content in fatty acids, proteins and fiber, which contribute to its nutritional value.
Here we studied the secondary metabolites of hempseed aiming at identifying bioactive compounds that could contribute to its health benefits.
This investigation led to the isolation of four new lignanamides cannabisin M, 2, cannabisin N, 5, cannabisin O, 8 and 3,3′-demethyl-heliotropamide, 10, together with ten known lignanamides, among which 4 was identified for the first time from hempseed.
Structures were established on the basis of NMR, HR-MS, UV, IR as well as by comparison with the literature data.
Lignanamides 2, 7, 9-14 showed good antioxidant activity among which 7, 10 and 13 also inhibited acetylcholinesterase in vitro.
The new identified compounds in this study added to the diversity of hempseed composition and the bioassays implied that hempseed, with lignanamides as nutrients, may be a good source of bioactive and protective compounds.” http://www.ncbi.nlm.nih.gov/pubmed/26585089
“Alzheimer’s Disease (AD) is the most common single cause of dementia in our ageing society. On full assessment and diagnosis of AD, initiation of an AChe inhibitor is recommended as early as possible, it is important that AChe inhibitor therapy is considered for patients with mild to moderate AD.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2014378/
