Arecoline is an alkaloid-type natural product found in betel nuts from the betel palm (Areca catechu).[1] It is an oily liquid that is soluble in water, alcohols, and ether.

In many Asian cultures, the betel nut is chewed to obtain a stimulating effect. Arecoline is the primary active ingredient responsible for the central nervous system affects which are roughly comparable to those of nicotine, which has a similar chemical structure. Arecoline is known to be an agonist of muscarinic acetylcholine M1, M2 and M3 receptors,[1][2][3] which is believed to be the primary cause of its parasympathetic effects (such as pupillary constriction, bronchial constriction, etc.). This article is about the chemical compound. ... Amanita muscaria from which muscarine was isolated Acetylcholine - natural agonist of muscarinic and nicotinic receptors. ... The chemical compound acetylcholine, often abbreviated as ACh, was the first neurotransmitter to be identified. ... Anatomy and Physiology of the A.N.S. In contrast to the voluntary nervous system, the involuntary or autonomic nervous system is responsible for homeostasis, maintaining a relatively constant internal environment by controlling such involuntary functions as digestion, respiration, and metabolism, and by modulating blood pressure. ...


Owing to its muscarinic and nicotinic agonist properties, arecoline has shown improvement in the learning ability of healthy volunteers. Since one of the hallmarks of Alzheimer's disease is a cognitive decline, arecoline was suggested as a treatment to slow down this process and arecoline administered via i.v. route did indeed show modest verbal and spatial memory improvement in Alzheimer's patients, though due to arecoline's possible carcinogenic properties, [4] it is not the first drug of choice for this degenerative disease. [5]

Arecoline has also been used medicinally as an antihelmintic (a drug against parasitic worms).[6] Anthelmintics (in the U.S., antihelminthics) are drugs that expel parasitic worms (helminthes) from the body or kill them. ...

Arecoline is a stimulant which acts on the parasympathetic nervous system to induce a range of different effects including a heightened sense of awareness as well as increased salivation, heart rate, blood pressure, body temperature and intestinal function.
Regional brain metabolic responsivity to the muscarinic cholinergic agonist arecoline is similar in young and aged Fischer-344 rats.

Betel Nut : by Ray Sahelian, M.D., Benefits of Betel Nut (1564 words)
The plant extract was subjected to activity-directed fractionation and all resultant fractions showed atropine-sensitive spasmogenicity in rabbit jejunum and also AChE inhibitory effect at doses similar to that for the parent crude extract, the ethyl acetate fraction being slightly less potent.
Some of the known constituents of betel nut, including arecoline, were tested for the possible inhibitory effect on AChE, none were found active.
In study 2, 15 Indian men received gels delivering 0 or 10 mg arecoline after consuming a 2.5 MJ meal, and the same protocol was then applied as in study 1.
