Punicalagin (Pyuni-cala-jen) is an ellagitannin, a type of phenolic compound. It is found as alpha and beta isomers in pomegranates (Punica granatum), Terminalia catappa, Terminalia myriocarpa,[1] and in Combretum molle, the velvet bushwillow, a plant species found in South Africa.[2] These three genera are all Myrtales and the last two are both Combretaceae.
Research
Punicalagins are water-soluble and hydrolyze into smaller phenolic compounds, such as ellagic acid.
There were no toxic effects in rats on a 6% diet of punicalagins for 37 days.[3] In laboratory research, punicalagins had carbonic anhydrase inhibitor activity.[4]
