Significance of Ellagitannin
Ellagitannin, a class of tannins found in various plants, is studied for diverse biological activities. Research highlights its protective role against gastric ulcers and its ability to be oxidized by bacterial membranes. Derived from gallic acid, it exhibits activity against parasites. Specific phenolic compounds abundant in red raspberries are identified as ellagitannins. It's a hydrolysable tannin yielding ellagic acid upon hydrolysis, found in pomegranate seed extract with antioxidant properties. Geraniin is a prominent example in rambutan rind extracts, formed by esterification of glucose with hexahydroxydiphenic acid.

(1) Ellagitannins from natural sources were found to be more effective than using purified ellagic acid, contributing to the antioxidant properties of mango seed kernel.[9] (2) Ellagitannins are complex polyphenols, and ellagic acid and urolithins have been identified after strawberry fruit intake, produced during the metabolism of ellagitannins.[10]
