pomegranate ellagitannin
The pomegranate ellagitannins, which include punicalagin isomers, are ellagitannins found in the fruit, rind (peel), bark or heartwood of pomegranates (''Punica granatum'').
== Chemistry ==
As the chemistry of punicalagins became known it was found to be not unique to pomegranate. Punicalagins are present in numerous species of the genus ''Terminalia'', species ''chebula'' Retz. (“Fructus Chebulae”), ''myriocarpa'', ''catappa'' and citrina (tropical flowering trees historically used in African traditional medicine for antibiotic and antifungal purposes). They have also been isolated from ''Cistus salvifolius'' (a Mediterranean shrub) and ''Combretum molle'' (an African shrub).
Pomegranate fruits natural phenols can be extracted with ethyl acetate and fractionation can afford the ellagitannin punicalagins.
