Raw betel nut has the highest content of this ingredient. The rest are Arecaidine, Guvacine, Guvacoline, Arecolidine, Homoarecoline and Isodemethylarecoline Isoguvacine etc. Arecoline 0.3% ~ 0.63%, arecoline 0.31% ~ 0.66%, desmethylarecoline 0.03% ~ 0.06%, desmethylarecoline 0.19% ~ 0.72%.

2. Fatty acids: Betel nut seeds contain about 14% fat, of which the fatty acids with higher content are linoleic acid 32.12%, oleic acid 29.50%, and palmitic acid 27.70%, indicating that the fatty acids of areca nut contain both high levels of saturated fatty acids (palm acid) and contains a high content of polyunsaturated fatty acid (linoleic acid). Other fatty acids include pelargonic acid, benzoic acid, and n-pentadecanoic acid.

3. Tannins: The tannins in areca nut are condensed tannins, which are flavanol derivatives and exist in combination with arecoline, with a content of about 15%. Areca nut contains a variety of condensed tannins, including Arecatannin A1, Arecatannin A2, Arecatannin A3, Arecatannin B1, Arecatannin B2 and Arecatannin C1, etc.

Flavonoids: isorhamnetin, quercetin, liquiritin, (+)-catechin, 5,7,4'-trih y droxy -3',5'-dimeth oxy flavanone; phenolics: trans Formula resveratrol, ferulic acid, vanillic acid; 3 steroidal components: peroxyergosterol, stigmaster-4-en-3-one, β-sitosterol and 2 other components cycloaltinol, de-O -methyllasiodiplodin.

Arecoline: Colorless and odorless oily liquid. Boiling point: 209℃, 92℃~93℃ (7mmHg), 105℃ (12mmHg). Miscible with water, ethanol and ether, soluble in chloroform. Hydrochloride is needle-shaped crystal with a melting point of 158°C and is soluble in water and ethanol.

Arecoline: flake crystal (dilute ethanol), melting point 232°C (decomposition). Easily soluble in water and dilute alcohol, almost insoluble in absolute ethanol, chloroform, ether and benzene. The melting point of hydrochloride is 251°C, its needle-like crystal decomposition point is 263°C (rapid heating), and it is easily soluble in water.
