Infobox references

Punicalin is an ellagitannin. It can be found in Punica granatum (pomegranate)[1] or in the leaves of Terminalia catappa, a plant used to treat dermatitis and hepatitis.[2][3] It is also reported in Combretum glutinosum, all three species being Myrtales, the two last being Combretaceae.

It is a highly active carbonic anhydrase inhibitor.[4]

Chemistry

The molecule contains a gallagic acid component linked to a glucose.
