Tellimagrandin II

It can be found in Geum japonicum and Syzygium aromaticum (clove).

[1] Tellimagrandin II is an isomer of punicafolin or nupharin A, but the hexahydroxydiphenoyl group is not attached to the same hydroxyl groups in the glucose molecule.

[1] It is formed by oxidation of pentagalloyl glucose in Tellima grandiflora by the enzyme pentagalloylglucose: O(2) oxidoreductase, a laccase-type phenol oxidase.

[3] It is laccase-catalyzed dimerized to cornusiin E in Tellima grandiflora.

[4][5] It has an extremely weak basic(essentially neutral) compound.
