Casuarictin
Encyclopedia
Casuarictin is an ellagitannin
, a type of hydrolysable tannin. It can be found in Casuarina
and Stachyurus
species.
The molecule is formed from tellimagrandin II
, itself formed from pentagalloyl glucose via oxidation. Casuarictin is transformed into pedunculagin via loss of a gallate group, and further into castalagin
via glucose pyranose ring opening.
Ellagitannin
The ellagitannins are a diverse class of hydrolyzable tannins, a type of polyphenol formed primarily from the oxidative linkage of galloyl groups in 1,2,3,4,6-Pentagalloyl glucose...
