Casuarictin is anellagitannin, a type of hydrolysable tannin. It can be found inCasuarina andStachyurus species.[1]
It is formed from twohexahydroxydiphenic acid units and onegallic acid unit linked to aglucose molecule.
The molecule is formed fromtellimagrandin II, itself formed frompentagalloyl glucose via oxidation. Casuarictin is transformed intopedunculagin via loss of a gallate group, and further intocastalagin via glucose pyranose ring opening.
Sanguiin H-6 is a dimer,Lambertianin C is trimer andlambertianin D is a tetramer of casuarictin.
