Grandinin is an ellagitannin. It can be found in Melaleuca quinquenervia leaves^[1] and in oaks species like the North American white oak (Quercus alba) and European red oak (Quercus robur).^[2] It shows antioxydant activity.^[1] It is an astringent compound.^[3] It is also found in wine, red^[4] or white,^[5] aged in oak barrels.

It is a castalagin glycoside^[6] by binding of the pentose lyxose.^[3] It contains a nonahydroxytriphenic acid moiety.

It suppresses the phosphorylation of the epidermal growth factor receptor in human colon carcinoma cells.^[6]
