The pomegranate ellagitannins, which include punicalagin isomers, are ellagitannins found in the sarcotestas, rind (peel), bark or heartwood of the pomegranate fruit (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

Pomegranate fruits natural phenols can be extracted with ethyl acetate and fractionation can afford the ellagitannin punicalagins.^[4]
