ABSTRACT

Morinda citrifolia (noni) fruit juice has exhibited a variety of biological activities in human clinical trials, indicating that it influences multiple systems of the body. Since the 1990s, the endocannabinoid system (ECS) has been found to modulate the activity of other organ systems. To investigate noni’s potential impact on the ECS, extracts from freeze-dried noni fruit were evaluated in fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL) inhibition assays. The ethyl acetate extract demonstrated the greatest activity against both enzymes. Lignans in this extract also inhibited enzyme activities, with americanin A being the most active in both assays. Americanoic acid and 3,3’-bisdemethylpinoresinol were the next most active compounds. These results suggest that lignans in noni fruit may influence endocannabinoid levels within the body via FAAH and MAGL inhibition. This reveals another set of probable mechanisms of action by which noni juice affects human health.
