Description

ellagitannin: structure; precoxin A/ praecoxin A is a purified ellagitannin [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

ellagitannin : A form of hydrolysable tannin produced from ellagic acid. Ellagitannins are glucosides which are readily hydrolysed by water to regenerate ellagic acid when the plants are eaten.

Research Excerpts

Overview

Ellagitannin is a common compound in food and herbs. There are few detailed studies on the metabolism of purified ellag itannins. Ellagit Annins are phenolic compounds with biological activities.

Bioavailability

The bioavailability of ellagitannins, including punicalagin, has not been previously described in humans. The mechanisms of observed therapeutic effects following oral administration still remain unclear.
