Arecatannins are a class of condensed tannins in the sub-class procyanidins contained in the seeds of Areca catechu also called betel nut. The arecatannin-type natural products from Ceylonese cassia bark and Areca seed are examples of polyphenols by both current definitions, and fit the distinct definition of a polymeric phenol as well.
Known molecules
The following six known arecatannins have been detected in A. catechu seeds.
