Flavono-ellagitannin

The Flavono-ellagitannins or complex tannins are a class of tannins formed from the complexation of an ellagitannin with a flavonoid. Flavono-ellagitannins can be found in Quercus mongolica var. grosseserrata.[1][2]

## Examples

[edit]

* Acutissimin A
* Acutissimin B
* Camelliatannin G[3]
* Epicutissimin A
* Mongolicains
* Mongolicain A[4]
* Mongolicain B
